DATADVANCE development team makes available pSeven 6.14, a new version of the company's flagship platform for data analysis and optimization. In this update, the company has devised design space exploration and predictive modeling enhancements, extended integration capabilities and connected interactivity between some viewers. The company also deployed a few usability updates and introduced a new licensing format. 

Design Space Exploration Enhancements

This release refines Design Space Exploration capabilities that empower engineers to explore various design alternatives and easily find optimal solutions. The resulting new block has the following key features:

The entire setup of optimization and design of experiments (including adaptive) techniques are under the hood. You can combine strategies and switch between techniques when solving your design tasks.

SmartSelection is activated by a button and automatically selects the best approach based on the properties of your design task.

Four new techniques implemented: Surrogate-based optimization, Gradient-based optimization, Adaptive design for GP and Diagonal sampling.

Predictive Modeling Enhancements

Some notable changes are outlined below:

Implemented a new method of model training parallelization which utilizes multi-core CPUs in a much more efficient way, training candidate models in parallel. This feature noticeably speeds up model training in case of multiple outputs or in the presence of categorical variables. It is also supported in the manual training mode and in the ApproxBuilder block, where it can be controlled using the specific option.

Added an ability to build more accurate models in cases when values of some training outputs are exponentially distributed, thanks to the better support for automatic log transformation of training data.

Improved the special data analysis algorithm to prevent oscillations of model outputs when a smooth model is required. As a result, the best approximation technique is selected according to the expected landscape of the model.

Integration Block Updates

The topical issues here include:

Added the STAR-CCM+ block which enables integration of STAR-CCM+ simulations into a workflow, supports StarCAD, CFD and Turbo Wizard parameters in STAR-CCM+ and can run simulations on a remote STAR-CCM+ server.

Introduced the FMI model block to integrate Functional Mock-up Units for Co-Simulation into workflows.

Usability Improvements

pSeven 6.14 comes with some usability improvements:

Navigate to a specific row in the Sample viewer (the command is triggered using the Ctrl + G shortcut) and enjoy the accelerated viewer performance when working with large datasets.

Set name prefixes to data series when importing data from CSV or Excel files.

Select multiple items in the model tree of Approximation model and CAD blocks. Selected items are automatically shown on the Variables or Properties panes.

Add screenshots from the simulation on 2D plots to visually assess the design points.

Quickly view the results of your testing operations—values of variables read from the template and a preview of changes applied by the Text block to the template.

Use a new automatic layout for blocks and links in your workflows.

Maximize all block configuration dialogs.

Command-Line Workflow Integration

The update provides a practical and easy way to integrate pSeven as a part of some external process. Now you can start workflows from the command line using pSeven’s batch mode (p7batch). Its notable features are:

Workflows are started from a command line; there is no need to open a project in pSeven or click any GUI buttons.

Running a workflow in batch mode does not show pSeven’s graphical interface so that it can be used even on systems without a graphical environment.

pSeven running in batch mode could use a pSeven Runner license instead of full license.

Licensing

This version introduces a new license format that provides a simple and flexible way to deploy and use pSeven for solving various engineering problems. Moving to pSeven 6.14 requires an updated license file. Licenses issued for the previous versions of pSeven are not compatible with pSeven 6.14 and above. New licenses files will be sent shortly to customers with active technical maintenance period. This release also brings many updates to the chapters of the user manual and resolves a number of issues and bugs to improve overall customer experience with the product.
