PERMAS is a generally applicable finite element program . It is being further developed by INTES GmbH, Stuttgart and is particularly suitable for linear and non-linear structural mechanics calculation , fluid-structure coupling in acoustics , for the analysis of electromagnetic fields and heat conduction including radiation exchange . There is also a fully integrated optimization functionality for topology / dimensioning / form finding (also in combination) and for a robust optimum (stochastic parameters). No graphical interaction is intended as pure calculation software. This is done using separate programs.

description

The native input takes place via its own data formats for the model description and the control of the calculation. In addition to its own GUI, VisPER , numerous interfaces to pre- and postprocessors such as B. ANSA, HyperMesh, MEDINA , Simcenter (NX), as well as direct (input) interfaces to solvers such as Abaqus or Nastran a flexible use in the simulation process chain. This also includes an efficient connection to multi-body simulation (MKS, morebms). The IDEAS universal file format can also be used for comparison with measurement models. A task graph based, general parallelization is available especially for demanding and complex tasks . A cloud computing service is available with the Open Telecom Cloud . In addition to Linux , Windows platforms are also available as operating systems .

history

The roots of PERMAS date back to the early 1960s, when the ASKA program system was developed at the Institute for Statics and Dynamics of the University of Stuttgart under the direction of John Argyris as a pioneering software for this technology. Some of the authors decided to spin-off in 1984 in order to enable continuous development. At the end of the 1980s, a new generation of programs was implemented, which was subsequently marketed for the first time as PERMAS Version 5 in 1993. This new development took into account the stormy development on the hardware market (e.g. with vectorization and RISC architecture) and formed the basis for a general parallelization concept: PTM (Parallel Task (graph) Manager). Since then there has been an extensive functional expansion, also in the context of research projects, e.g. B. Optiamix

In addition to its headquarters in Germany (Stuttgart), INTES is also active with its own branches in France and Japan. There are sales partners in other countries (such as China, Korea, India).
