		  <summary type="html"><![CDATA[NEi Nastran is an engineering analysis and simulation software product of NEi Software (formerly known as Noran Engineering, Inc.) Based on NASA&#39;s Structural Analysis program, the software is a finite element analysis (FEA) solver used to generate solutions for linear and nonlinear stress, dynamics, and heat transfer characteristics of structures and mechanical components. NEi Nastran software is used with all major industry pre and post processors including Femap, a product of Siemens PLM Software, in house brands NEi Fusion, and NEi Works for SolidWorks.<br/><br/><br/> <br/>History<br/>Main article: NASTRAN<br/>The o&#114;iginal NASTRAN program came out of NASA’s need to develop a common generic structural analysis program that would be used by all of the centers supporting the space program. A specification was written and a contract was awarded to Computer Sciences Corporation for development of NAsa STRuctural ANalysis (NASTRAN) software. NASTRAN was released to NASA in 1968. In addition to NEi Nastran, commercial versions of are also available from Siemens PLM Software (NX Nastran) and others.<br/><br/>Improvements<br/>Main article: Finite element analysis<br/>In the late 1960’s, Finite Element Analysis software was confined to run on expensive mainframe computers and highly trained specialists were needed to apply the program. In this environment, the aerospace industry was the typical user because they had critical projects which could justify the resources FEA demanded. With improvements to the software and wider use of mainframes, FEA technology gradually spread to large corporations that could afford funding the huge investment in hardware, software, and a dedicated FEA staff. Usage spread from primarily aerospace and military applications to the automobile and maritime industries.<br/><br/>The microprocessor revolution and the advent of Personal Computers (PCs) in the 1980’s brought tremendous improvements in computing power, significant reductions in computing costs, and the steady development of numerical methods and algorithms. In the mid 1980’s, Noran Engineering recognized the long term advantages and impact that the PC hardware revolution could have on the engineering analysis field and embarked on a project to significantly enhance and modernize the o&#114;iginal NASTRAN code and port it to PCs.<br/><br/>The first commercial version of NEi Nastran for use on PCs was released in 1990. The new code had a number of changes in architecture and programming language compared to legacy Nastran written o&#114;iginally for mainframes. These differences were intended to take advantage of the dramatic changes in computer hardware taking place and provide the code with key strategic advantages for the new PC platform. For example, since the cost of memory was dramatically reduced it was feasible to perform many operations faster in memory that normally were only done on disk.<br/><br/>Another example concerns Nastran’s DMAP (Dynamic Matrix Abstraction Process). DMAP altars were o&#114;iginally intended to provide flexibility and customization capabilities. However, the method has lost much of its initial intent and advantage since it now requires familiarity with arcane computer code and maintenance revisions must be written each time a new Nastran software version is released. With NEi Nastran, DMAP routines are easily added to the main body of the program and maintenance revisions are not necessary.<br/><br/>Present day <br/><br/>NEi Nastran ScreenShotNEi Nastran V9.2 was released in March 2009. It incorporates over 85 customer driven enhancements including the following additions: nonlinear composite Progressive Ply Failure Analysis (PPFA), concrete material model, direct enforced motion, bolt preload, enhanced rigid element features, visualization support for various entities, automatic dynamic plots during nonlinear analysis, transparent max/min, and a new look and feel for its Editor tool.[1]<br/><br/>Applications<br/>Main Products<br/>NEi Nastran <br/>NEi Nastran is a powerful, general purpose finite element analysis tool with an integrated graphical user interface and model Editor which is used to analyze linear and nonlinear stress, dynamics, and heat transfer characteristics of structures and mechanical components. With specialized functions for Automatic Surface Contact Generation and Progressive Ply Failure Analysis, the software is frequently used for aerospace, maritime and automotive industries, particularly for analyzing composites. Features include control over mesh size and sensitivity, and the repair and editing of CAD geometry. NEi Nastran also offers Automated Surface Contact Generation and Automated Edge Contact Generation that allow separate meshing of components, mid-surfaced models, and off-set welds, then combine the meshes via proximity and user-defined settings.[2]<br/><br/>NEi Works <br/>NEi Works provides SolidWorks users with an embedded finite element modeling tool. It features the SolidWorks look and feel for all menus and functions, as well as integration between design and analysis.

		  <summary type="html"><![CDATA[<br/>Setting up and launching a parallel simulation has become much simpler and easier in CFD-FASTRAN V2007. This note discusses some of these developments. <br/><br/>Let’s start with things that have not changed. There are still two versions of CFD-FASTRAN solvers for parallel cases. The difference between the two versions is the underlying parallel communication mechanism, the choice of which is decided by the type of mesh used. Structured mesh models use MDICE (Multi-Disciplinary Computing Environment) and unstructured mesh models use MPI (Message Passing Interface). MDICE allows different applications to “talk” to each other and hence allows multi-disciplinary simulations such as coupled flow-structure simulations possible without integrating all features (disciplines) into a single code. <br/><br/>The following steps have been removed from V2007: <br/><br/>Need to run special scripts as part of the installation procedure <br/>Need to launch MDICE registry and daemons <br/>Need to launch parallel job only from the command prompt using different scripts such as CFD-FASTRAN-SOLVERP and fastran-mpi <br/>These operations are automatically performed by the script behind the scenes, and hence the user does not have to perform these steps. <br/><br/>The following options have been added to setup parallel cases for CFD-FASTRAN: <br/><br/>Can setup both MDICE-based and MPI-based simulations using the improved parallel configuration panel (located on the Run tab) <br/>Can launch a parallel job (MDICE o&#114; MPI) from CFD-FASTRAN-GUI o&#114; command prompt <br/>A single command-prompt command for all (serial and parallel) FASTRAN job submissions (CFD-FASTRAN-SOLVER –dtf &lt;file name&gt;) <br/>Can easily edit available hosts through CFD-FASTRAN-GUI <br/>Now, we look at some of the settings available in the new Parallel Setup Panel. This panel can be reached through the Configure Parallel Run option available in the Run tab when parallel is sel&#101;cted as the Run Type. Depending on the type of mesh used, the MDICE o&#114; MPI panel will become available. The Host List can be edited by clicking on the Edit button on the left hand side of the parallel setup panel. <br/><br/>In MDICE-based parallel simulations, the Distribute Zones button in the Zone Assignment box performs load balancing based on the number of cells. This just assigns available zones to different nodes and no domain decomposition is performed. The load factor column gives an indication of the maximum speed up that can achieved through a particular distribution. The user can review this and reassign the zones to get as close to a load factor of 1 for all zones. Therefore, it is advisable that the user plans ahead to avoid the possibility of having large zones that tilts the load factor unfavorably. Also note that the chimera and stress zones should be assigned to an exclusive processor. At this time, chimera and stress calculations are performed in serial only. <br/><br/>In MPI-based parallel simulations, domain decomposition is performed using dtf_decompose. Several options for domain decomposition are available. The Multilevel Graph Partitioning Scheme provides high quality partitioning with less CPU time and performs work load balancing. If you would like to know more about domain decomposition, please follow this link. <br/>]]></summary>

		  <summary type="html"><![CDATA[New functionality: Release 2.1<br/><br/>Faster engineering, securer data handling, convenient modeling and flexible licensing are now at hand with the new upgrade of the FRIENDSHIP-Framework. Release 2.1 includes new functionalities, operational refinement and strategies for efficient design, which help you to perform better and to cr&#101;ate superior products. Functionalities that boost your design contribute to an overall slimmer design process. A design process that raises the bar for efficiency, user-friendliness and applicability—and that strengthens your and your designs&#39; competitive performance.<br/><br/>In brief, the FRIENDSHIP-Framework 2.1 provides<br/><br/>Faster engineering through remote computing<br/><br/>Safer file handling through enhanced data management<br/><br/>Individualized work through the Configuration Wizard<br/><br/>Boosted surface design through hands-on point manipulation and validation<br/><br/>Flexible operation through extended licensing modes<br/><br/>Fully-parametric design of turbomachinery blades<br/><br/>A number of additional solutions for quicker, better and handier design<br/><br/>Clearly, each application yields major savings in time, cost and design resources. Yet their combination will boost your design process to top performance and superior products.<br/><br/>What does that mean, what do you gain?<br/><br/>Remote computing o&#114; distributed computing, as it is also referred to, is a technology that allows you to effectively include available hardware resources in your design process, thereby speeding up the overall computational time and consequently minimizing total development time. How does it work? The idea behind remote o&#114; distributed computing is to split and dispatch open computational tasks among idle hardware resources. These may be remote computers, far workstations o&#114; distant office hardware. Remote computing can employ virtually all available processing units. The distribution and result management&nbsp;&nbsp;is handled through Secure Shell (SSH) protocol, which connects remote computers. Generally, the computation time of processes supported through remote computing is reduced by the factor of additional powerful hardware components. Especially for computationally intensive tasks, the enormous relief and the savings in time and cost this technology yields are overwhelming.<br/><br/>Applied to the FRIENDSHIP-Framework, this technology allows the parallel execution of integrated tools on your local computer o&#114; on remote machines. You can use available multi-core processors (CPU) to execute multiple instances of the extern tools that are integrated into the FRIENDSHIP-Framework. You may well start the external tools on remote computers through the SSH protocol. With respect to large operations like variant calculation o&#114; hydrodynamic optimization, distributed computing streamlines and consolidates your workflow massively. <br/><br/> <br/><br/>Enhanced data management<br/><br/>Handling and storing data is a key challenge in software development. Release 2.1 answers to this quest with few smart solutions, which are designed to make you feel relaxed while operating the FRIENDSHIP-Framework. <br/>With release 2.1, the current project file is up&#100;ated and kept consistent to the project state. That helps managing system failures. Crash recovery for projects is a new functionality, which will recover your project to its latest state in case of the odd system collapse.<br/>The incremental saving of project data additionally eases your work flow as it spares you long saving procedures, which can be quite straining especially when operating large projects. For such another development is a real asset: the FRIENDSHIP-Framework now runs on reduced memory. This is an obvious plus especially if you sample numerous designs in one project. Enhanced data management also means that projects are altogether loaded faster, which again reduces idle time significantly.&nbsp;&nbsp;<br/><br/><br/><br/><br/>Configuration Wizard<br/><br/>A new development for faster data exchange is the Configuration Wizard. This feature supports the smart and easy set up of input data for external tools, which&nbsp;&nbsp;run within the FRIENDSHIP-Framework. The content and o&#114;der of each wizard page can be configured by the provider of the corresponding definition and be customized to individual preferences accordingly. The Configuration Wizard translates the concept of the FRIENDSHIP-Framework as the designer&#39;s configurable workbench meaningfully into your&nbsp;&nbsp;benefit.<br/><br/><br/>Extended license modes <br/><br/><br/>Matching the requirements of project engineering, release 2.1 comes with extended licensing modes. Now the FRIENDSHIP-Framework can be licensed with different temporal and functional scope. Float licenses are a flexible solution and cost saving alt&#101;rnative for mobile and group work. Licensed for one o&#114; more workstations, the FRIENDSHIP-Framework can be run on several work stations. In comparison to regular licenses, which are hardware-bound and which allow the installation and use of the software on the very registered computer, the float license enables the software use on several computers, even mobile devices, depending on the license scope. The FRIENDSHIP-Framework may now also be rented for a limited time frame. The rent license is particularly attractive for temporary project based work. <br/><br/><br/><br/><br/>Point manipulation<br/> Point management and the general visualization of geometry are easier and more convenient in release 2.1. For instance, the principal plane can be made visible even if the user does not operate in main view. Here, he can cr&#101;ate and handle points along the displayed plane. Point creation is handier, work steps are consolidated and altogether faster. This is true also for the establishment of curves such as B-Spline and NURBS, which can now be generated through simple mouse operation. Using the menu bar is nonetheless available. Set your preferences and personalize the FRIENDSHIP-Framework, make it work the way you want it to work: facilitating an excellent engineering environment of utmost comfort is our prime principle and guides our development. Hence, a number of extra improvements have been added, which will surely make your operation of the FRIENDSHIP-Framework more convenient, more relaxed, more efficient.<br/><br/><br/>Special functionality for turbomachinery<br/> The Stream Section, a new curve type for the design of efficient blade surfaces like compressor blades, allows fully-parametric section design in length-preserving and angle-preserving systems. It facilitates the fully-parametric modeling of stream surfaces in comprehensive and convenient steps. <br/><br/>General <br/>The User Guide is now available as a comprehensive handbook in printer-friendly format (PDF). It provides a consolidated overview of the scale and scope of functionality of the FRIENDSHIP-Framework and helps you get a read and too a quick start by showcasing numerous exemplary applications&nbsp;&nbsp;for hull design and turbomachinery components.

		  <summary type="html"><![CDATA[ <br/>In certain applications, different regions of the computational domain experience flow conditions that are so different that it is very difficult for any solver to produce sufficiently accurate results at the limits. In many situations, such problems can be separated and solved using loosely coupled solvers. Each solver is chosen to provide highly accurate solutions for the prevailing flow regimes. This kind of flexibility and fidelity is necessary when users are moving towards simulation-driven design solutions. <br/><br/>ESI&#39;s CFD-FASTRAN, a compressible flow solver, is ideally suited for high-speed external aerodynamics problems while the multi-physics solver CFD-ACE+ is best for heat transfer problems involving conduction, convection (natural and forced) and radiation. Several users may already be aware of FASTRAN/ACE+ coupling for fluid-structure interaction (FSI) simulations. From v2009.2, users can take advantage of a new FASTRAN/ACE+ coupling for heat transfer simulations. A typical application example (see figure 1 below) on thermal environment simulation is presented to help you get started on applications wh&#101;re you can use this feature. <br/><br/> <br/><br/>Figure 1.&nbsp;&nbsp;Re-entry capsule at angle of attack. Mach number contours are displayed for the external flow;<br/>internal flow is represented by velocity vectors; capsule thickness and internal component show temperature distribution. <br/><br/>A large amount of aerodynamic heating is generated over hypersonic vehicles during re-entry. Thermal Protection System (TPS) materials are employed to prevent the heat from conducting into the internal cabin, which holds electronic devices, passengers, and other vital components. As a time-dependent process, the material making up TPS is at a low temperature and “soaks up” the heat – the conductivity of the material transports the heat (from the vehicle surface) through the thickness and into the internal volume. The material will also radiate some of the heat back to the flow – the amount depending on the emissivity of the material. A primary concern is to estimate the effects of aeroheating on the internal volume of the capsule, and its effect on electronic devices, passengers and cooling systems. In this application, typically the external flow is hypersonic in nature, wh&#101;reas the flow within the capsule is a very low-speed flow dominated by natural convection. In addition to hypersonic aerodynamic heating, several other physics including heat conduction, natural convection and radiation have to be accurately modeled. CFD-FASTRAN solves for the external hypersonic flow and CFD-ACE+ solves for internal flow, heat conduction, convection and radiation. Exchange of heat flux/temperature data between the CFD-FASTRAN and CFD-ACE+ solvers occurs at defined interfaces. A simple demo case can be downloaded here.<br/>]]></summary>
