DATADVANCE development team is pleased to announce the release of pSeven 6.6, the most complete design space exploration platform up to date, for every expertise.

The newest release of pSeven is more feature-packed than ever, and is far superior even to the previous versions of pSeven in terms of capabilities it brings for every expertise. pSeven 6.6 introduces the interactive Predictive Modeling Toolkit, built on top of the powerful MACROS algorithmic core and tightly integrated into the Analyze mode, as well as a variety of long-expected feature updates and improvements, further increasing pSeven’s performance, stability, and ease of use.

Predictive Modeling Toolkit, the latest addition to pSeven’s wide range of data analysis and post-processing tools available in the Analyze mode, is a set of interactive tools that enables thorough data analysis, approximation model training, model validation and evaluation with high accuracy and less effort.

What makes predictive modeling and data analysis in pSeven easily available for every expertise?

Use all data sources you want: get your data from Excel using the updated and improved Excel import tool, read it from text files of virtually any tabular format, or load it from your pSeven project database.
Train your models with a click of a button! With the new SmartSelection technology implemented in the Predictive Modeling Toolkit, pSeven automatically selects the best training method and adjusts its parameters in order to train the most accurate model.
State-of-the-art modeling algorithms allow you to add a priori knowledge an subjective information to your data – a feature unique to pSeven. For example, you can set noise levels for data samples, or assign higher weights to important or more accurate sample points.
Fine-tune model builder settings: advanced users will love the amount of settings provided in the Model Builder. If you want to direct the modeling process your way, pSeven gives steering to you! Not sure where to go next? The SmartSelection technology will be your co-pilot!
Validate your models in a clean and intuitive way using the Model Validator tool to visualize model accuracy metrics.
Evaluate a model you have trained and view the results immediately, thanks to the tight integration of the Predictive Modeling Toolkit and other pSeven’s data analysis tools, or add this model to a pSeven workflow automating mass calculations.
If you are a multitasker, pSeven is too: train multiple models, validate and evaluate them in parallel, all in the convenient multifunctional pSeven’s Analyze interface.
Your models are yours to use wherever you want: export model code to MATLAB or C, compile it to a DLL and call it from Excel spreadsheets.
Automate everything you wish, even model training and export: pSeven supports approximation workflows thanks to the std.ApproxBuilder block. In pSeven 6.6 std.ApproxBuilder also received significant updates and now supports all features available in the Predictive Modeling Toolkit, including the support for incremental model training, data sample weighting and processing noisy data.
As well as all previous releases, pSeven 6.6 is aimed for higher flexibility and a wider feature set while staying backwards compatible – both in terms of program compatibility and continuing support of data analysis, optimization, and process integration methods.

pSeven 6.6 includes an updated robust optimization algorithm for problems that include computationally expensive objectives. Efficiency of the new method is based on more intense use of modeling capabilities, which allows optimizer to reduce the required number of objective function evaluations.
Updated PTC Creo integration block provides full support for integration with PTC Creo 3.0.
Updated SolidWorks integration block with improved error handling and higher stability.
Updated Python integration block with simplified import of third-party Python modules, further increasing pSeven’s capabilities for scientific computing.

SHIPFLOW version 6 is released!
SHIPFLOW 6 comes with a new module for computing ship motions in waves and the SHIPFLOW RANS solver is up to 10 times faster than its predecessor.
SHIPFLOW MOTIONS is a new flow solver for computing ship motions in waves. It is a time accurate fully non-linear boundary element method which can be used to compute ship motions and added resistance in regular and irregular waves as well as wave resistance, sinkage and trim in calm water. Typical results are time series and response amplitude operators. We believe that the method will be a useful tool for ship designers with higher accuracy than traditional potential flow methods while at the same time being faster than the available RANS methods.
The SHIPFLOW 6 RANS solver XCHAP is now up to 10 times faster than its predecessor (version 5.2). A resistance computation can be run within 15 minutes and a self-propulsion simulation within 1 hour on a workstation. The increased solver performance and the efficient self-propulsion capability in SHIPFLOW makes automatic shape optimization of ship sterns feasible for ship designers. The delivered power can be optimized with self-propulsion simulations taking the two, often conflicting, aspects of resistance and propeller efficiency directly into account. SHIPFLOW 6 and CAESES* have been used successfully for stern shape optimizations of mono and twin-skeg hulls.
“We are thrilled to offer the new efficient capabilities for optimizing the ship hull to reduce the delivered power and improve the performance in waves”, said Leif Broberg, managing director of FLOWTECH International AB. “These optimizations can now be used by our customers in their ship design process and we hope that it will contribute to more energy efficient and safer ships in the future”.
FLOWTECH International AB with its product SHIPFLOW is the market leading developer and supplier of Computational Fluid Dynamics software packages for the Marine Industry. The package is designed to streamline the hull form, appendage and propulsion design process with a clear focus on optimisation in order to minimize energy consumption.
SHIPFLOW stems from long term research at FLOWTECH in close cooperation with SSPA and the Department of Shipping and Marine Technology at Chalmers University of Technology. Much of the development has been moved forward by joint projects with SHIPFLOW users and/or European and Nationally financed projects.
The number of licenses has grown steadily since the first version, SHIPFLOW 1.0, was released in 1991. Top shipyards, consultants and universities are among the SHIPFLOW users. Developed by naval architects, physicists and numerical analysts the software is optimised for ship hydrodynamics design. Specialisation means SHIPFLOW is efficient and user-friendly. Grids are automatically generated, resistance and propulsion data are presented in the naval architect’s way and the solvers are adapted for hull geometries. Over the past twenty five years SHIPFLOW has developed into the world standard for ship hydrodynamics CFD.
*Since 2007 FLOWTECH has had a close cooperation with Friendship Systems. Friendship Systems develop and market CAESES which is fully integrated with SHIPFLOW creating a very powerful tool for simulation driven design. SHIPFLOW Design is a subset of CAESES giving the user a complete pre and post processor but missing out on most of the optimisation and CAD tools which are available in the complete CAESES.

RTM-Worx2015发布
RTM-Worx 2015已经发布!这是一个稳定版本,您可以获得真正的3D功能。
**你可以通过边界面(象你通过封闭的曲线来定义面一样)来定义一个实体区域。
**3D渗透率采用如下方法定义:
-矢量[r3x,r3y,r3z]用来定义k33的方向,通常垂直于增强材料位于的平面。例如厚度方向。当这个平面已经建立,矢量[r1x,r1y,r1z]在该面上的投影就是k11的方向。k22的方向在由[r3x,r3y,r3z]定义的面内垂直k11。
**当你定义一个范围,一个3D四面体网格自动生成。网格“e/R”参数用来定义四面体单元的边和半径的比率。网格可以通过插入附加的顶点来分割。用e/R=0来表示没有内部顶角(例如四面体网格只有在边界面上有顶角),用e/R=1来表示各向相同的网格。当网格生成器出现错误,你可以通过改变[Bounding box]选项的最大和最小参数来进行修复。
**在你开始运行模拟计算之前,用网格生成器面板上的[Clean]键对网格进行优化。当网格中包含薄片时就会出问题。这里的薄片是指质量为0%的单元(用着色显示中的单元质量选项或者收缩四面体单元可以看见他们)。通常薄片看起来象平面四边形,有非常小的体积(几乎为零)但没有短边。对于这样的单元,在厚度方向的压力降不能通过线性插值准确计算。
以下参数和选项可进行优化设置:
-cN=优化程序最大迭代次数
-qMin=可接受的最差单元(100%为最好,0%为极差)
-qEps=最差单元的网格优化措施。这将定义优化器将如何进行优化,甚至最差的四面体单元根本无法优化。
-[Add points]键:控制优化程序是否允许在区域内添加额外的节点。
**流道和壳单元可以与3D单元混和设置。

RTM-Worx的3D解算与其他-RTM的简单对比
 -RTM-Worx可以将1D线单元、2D壳单元与3D四面体单元混和使用。对于其他-RTM这是不可能的,你必须用3D单元来构建流道和通道。用RTM-Worx,你可以用区域边界面上的壳单元来构建网格,也可以用1D流道单元来构建流道和供料管。
 -与其他-RTM相比,RTM-Worx的网格需要的单元数更少。RTM-Worx采用更精确的单元,并且RTM-Worx解算器能够处理由大长宽比单元组成的非均等网格。而其他-RTM推荐用长宽比接近1的单元。如果你的模型中包含象渗透层这样的薄层,将会导致数量巨大的小尺寸单元。为了生成均向单元,单元的尺寸将由薄层的厚度来决定。在其他-RTM,中,一个矩形平板可能需要上百万3D四面体单元,而在RTM-Worx中,相同的构件要获得类似或更好的计算结果,仅需要1万四面体单元。这将严重限制 其他-RTM 模拟复杂零件的能力。
 -RTM-Worx解算器更快。加上所用的单元数量更少,计算时间上的差距是非常巨大的。
 -RTM-Worx解算器更强大,在处理一个模型中渗透率差距巨大时毫无问题。在其他-RTM中,为了完成模拟计算你必须对渗透率进行调整(例如在流道和网格中使用更低的渗透率)。尽管可以认为这样对计算结果没有大的影响,但这将意味这用户要调整物理特征,与之相关的特征可能完全丢失。
