Solver and CAD Neutral
PreSys provides users with a way to accept various CAD and solver formats. Native CAD data import is supported for CATIA, Unigraphics, Pro/Engineer, Solidworks, as well as IGES, STEP, SAT and VDA formats.
The solver-specific information allows unique capabilities of solvers such as NASTRAN, LS-DYNA, RADIOSS, PAM-CRASH, NISA, and ABAQUS, to be implemented in models.
PreSys uses an innovative template system to not only create solver-specific entities, but translate these entities between the various solver formats. This allows users to re-use model data created for other simulations in their current model. For instance, users may have access to NASTRAN models, which could then be imported to PreSys and re-used for development of an LS-DYNA simulation model.
PreSys for NISA
PreSys is now available to users world-wide. This offering will allow NISA users to take advantage of PreSys’ streamlined user interface, CAD interoperability and advanced graphics capabilities, thereby improving the overall NISA user experience.
PreSys will allow NISA users to create even complex finite element models easily. It is a full-featured, core mechanical engineering software solution that can be used on its own or with a variety of available add-on applications.
It also offers a scripting interface to automate processes and interact with 3rd party solutions, as well as a model explorer feature to provide in-depth data navigation.
