CAESES FRIENDSHIP-Framework 4.3.1 | 453.9 mb

FRIENDSHIP SYSTEMS released a new maintenance version of the CAD and optimization platform CAESES. With CAESES we strive to provide you with the most robust and reliable CAD solution for automated simulation studies.

Released CAESES 4.3:

In this first 2018 release, the internal geometry engine got a major update for advanced CAD modeling of complex and challenging shapes. In addition, we offer a new Parasolid export and a separate ANSYS add-on (ACT app) to plug CAESES into the ANSYS Workbench. Check out all the details - as well as important compatibility issues - and download the new version!

Fast and Robust Geometry

The CAESES geometry kernel received many great improvements both in terms of robustness and performance. There are also new features available, such as selecting solids based on their surface area. It allows you to always choose the same solid after the operation "Solid from Intersection". The former default setting was an unsorted list of generated solids where the order could potentially change in some situations during automated studies or optimizations.

The tolerance handling of trimming and Boolean operations has been improved. It provides you with a better default performance and robustness, so that in most situations you no longer need to care too much about global tolerances. See also the compatibility notes below.

In the context of curves and surfaces, check out this new feature for the interpolation curve: In addition to a list of points to be interpolated, you can also now set tangent information for the interpolation curve. For each input point, optionally use the squared brackets for creating a list, and then add the angle in degrees right next to the point or vector.

Parasolid Export

We are now offering a new add-on that allows you to export geometry by using the SIEMENS Parasolid format.

Show Results Only On Demand

So far, design results have been automatically loaded into CAESES� as soon as you click on a design in the tree or the result table. However, in situations where your result data are huge (which is often the standard situation of our customers), you potentially wait for several minutes until the data is loaded into the user interface. This can be annoying if you e.g. accidentally click on the design, or if you only want to check the design's variables and constraints setup.

In the new version, we decided to modify this behavior. As a new default, results are now loaded into CAESES� only on demand, which is a substantial change. There is a new icon next to the design name to click on, which triggers the data loading.

At the top of the GUI, there is also an additional button for auto-loading of result data. It gives you the former behavior again, e.g. to still conveniently browse through design results in the tree using only the arrow-keys.

In this context, we have also added the Results node to the optimization tab below the design engines, to give you quick access to this data when analyzing generated design candidates and their results. As a consequence, the design tree has been moved into a separate split window.

Multi-Objective Optimization: Result Pool

The global optimization method of the Dakota add-on which internally is a MOGA (multi-objective genetic algorithm) supports the re-use of existing designs. Previous runs can be optionally included to generate the initial population of the genetic algorithm. This avoids expensive recalculations of designs, if there are already existing suitable designs in your project. If you deactivate this result pool option, the former behavior is given, where a random number generator creates the design set for the initial population.

Similar to the MOGA, the NSGA-2 is now also able to use the result pool for all generations. In previous versions, only the first generation could be recycled.

Design Results Table: Fixed Column

The first column (design name) is now fixed so that you can scroll in the horizontal direction without loosing the corresponding names of the designs. Objective values receive a slightly darker background in the table to better distinguish them from simple evaluations.

New Demo Model: Impeller

We ship a new parametric geometry model of an impeller which can be used as a reference for custom designs. The model is prepared for automated studies with simulation tools. It contains the periodic segments of the flow domain (for CFD analysis) and of the solid domain (for structural analysis).

ANSYS ACT Extension and optiSLang Add-On

With this new CAESES version, we are releasing solutions to seamlessly integrate CAESES� with the ANSYS Workbench and optiSLang. We have moved our CAESES-ANSYS app from the beta phase into a productive phase: The fsc-script from CAESES now contains additional information that allows ANSYS users to easily connect CAESES to the ANSYS Workbench, and to automate geometry generation through the GUI of the ANSYS Workbench. There is a new tutorial available that explains how this integration works.

The new CAESES-optiSLang add-on is now also available, to plug CAESES into optiSLang. It provides fast access to the CAESES model parameters (i.e., the design variables) directly within the optiSLang GUI with just a few clicks, to control the automated geometry generation.

Changes Log CAESES 4.3.1:

New Features
- ANSYS ACT App: Workbench integration of CAESES now also works for *.fdbc files
- Results Table: Added option to display shortened names in first column
- ANSYS ACT App: Fixed export path information in fsc-file to make it run again without manual user interaction
- Batch Mode: Fixed non-GUI mode which had problems in a few very specific situations
- Ensemble Investigation: Fixed bounds not being correctly set with non-monotonous series of values
- Interpolation Curve: Fixed problem with setting points in special cases
- Project: Fixed saving of views in project
