Released CAESES 4.2.1

We have released version 4.2.1 of our geometry modeling and opti­miza­tion software CAESES®. Based on the fan­tas­tic feedback and excel­lent findings from our users, we have been able to fix a set of issues to further improve the software quality. There are also some new nice-to-have features that came in as user wishes which have been added to make your work with CAESES® a better expe­ri­ence. Thanks to everyone who par­tic­i­pated in giving us this great useful input. Here is a selec­tion of the things we’ve resolved and added in this main­te­nance version: 

Section Dis­cretiza­tion and Displacement

Plane sections are still often useful entities for hydro­sta­t­ics cal­cu­la­tions and for analysis tools like strip theory. We have improved our section gen­er­a­tion algo­rithms for more robust analysis, espe­cially of uncon­ven­tional hull forms like multi-hulls. For fast and precise dis­place­ment cal­cu­la­tions of arbi­trary floating struc­tures we have extended our surface inte­gra­tion method to Trimeshes and Breps. Compared to surface groups Breps have the advan­tage that the surface patch ori­en­ta­tion is taken care of by the Brep itself, while for surface groups the user still has to make sure that all surface normals point to the same side of the hull. 

Improved Handling of Invalid Designs

The behavior of the inte­grated opti­miza­tion methods has been improved when invalid designs are returned, which can happen e.g. if the meshing pro­ce­dure fails or the sim­u­la­tion run crashes. 

New Curve Functionality

We added a new curve feature for the creation of fair curves with intu­itive tangent control for given start and end angles — a simple but great com­ple­men­tary tool for shape changes during auto­mated studies. There is now also a new circle creation method avail­able for NURBS curves, to create a circular arc from a center and two given points — this was also a missing piece in the CAESES® tool box. The extrap­o­la­tion mech­a­nism of image curves (through the domain) has been improved to allow larger curve extrapolations. 

Software Con­nec­tion

Thanks to user feedback through the CAESES® forum, we were able to detect and repro­duce an impor­tant problem when copying files and direc­to­ries through our software con­nec­tor. This was an issue espe­cially for the OpenFOAM users, and is now resolved.

Changes Log and Download

There are many other items we’ve worked on for you, such as the clean-up behavior of design engines and improve­ments for brep objects, a modified export of FSC-scripts (to run CAESES® in batch mode). All details about new features, changes and bug fixes can be found in our changes log.
