PERMAS is a general-purpose finite element analysis (FEA) software with roots back to the 1960s. It is further developed by the company INTES GmbH, Stuttgart, Germany and is particularly suitable for linear and non-linear structural mechanics calculations, fluid structure interaction in acoustics, for the analysis of electromagnetic fields and heat conduction including radiation exchange. In addition, there is a fully integrated optimization functionality for topology/sizing/shape (also in combination) and for a robust optimum (stochastic parameters). Since 2008 PERMAS consists of two major products:

PERMAS the finite element solver and
VisPER (Visual PERMAS) a graphic model editor and postprocessor.

Description

The native input takes place via own data formats for the model description and the control of the calculation process. PERMAS has numerous interfaces to pre- and post-processors like e.g. ANSA, HyperMesh, MEDINA, Simcenter(NX)^[1], as well as direct (input) interfaces to solvers like Abaqus or Nastran. Direct interfaces to multi-body simulation (MBS, morebms,^[2]), as well as to fatigue assessment are also included. Moreover, boundary conditions of flow simulations e.g. with OpenFOAM may be taken into account. With the help of the IDEAS universal file format, a model updating with measurement models can be carried out. Especially for demanding and complex simulations a task graph based, general parallelization ^[3] is available. The Open Telecom Cloud provides a cloud computing service. PERMAS and VisPER use the open-source scripting language Python (programming language) for scripting and customization.

History

The roots of PERMAS date back to the early 1960s, when the ASKA (de) program system ^[4] was developed at the Institute of Statics and Dynamics of Aerospace Structures ^[5] at the University of Stuttgart under the lead of John Argyris as a pioneering software of this technology. In 1984, some of the authors decided to found a spin-off company in order to enable continuous development.^[6] At the end of the 1980s, a new program generation was realized, which was subsequently marketed for the first time as PERMAS Version 5 in 1993^[7]. This new development took into account the fast evolution 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)^[8]. Since then, an extensive functional expansion has taken place, also within the scope of research projects, e. g.: Optiamix^[9], EC project LISA ^[10], EU projects PERMPAR, PARMAT, and ASRA-HPC ^[11]

In addition to its headquarters in Germany (Stuttgart), INTES has its own subsidiaries in France and Japan.

Application Fields

Major applications: Stiffness, strength, contact, thermomechanical analysis ^[12], vibrations ^[13] (including random vibration and integrated active control ^[14]), acoustics^[15], rotor dynamics ^[16], stability (e. g. brake squeal^[17]), temperature and electromagnetic fields
Industries: Automotive, aerospace, tooling machines, shipbuilding and construction, wind turbine

Architecture

PERMAS is a modular software system based on a centralized software architecture.
A hypermatrix storage scheme is used as basis for vectorization and parallelization allowing to adapt matrices to caches und thus for an efficient handling of large simulation models.
Task Graph based parallelization scheme for hypermatrix operations with asynchronous I/O and in combination with (Nvidia) GPU.
Specific algorithms e.g. for contact analysis, coupled fluid-structure interaction^[18] and model testing.
Integrated optimization methods ^[19] , e.g. topology, shape, dimensioning and their combination, reliability analysis (robust design^[20] and sampling(DOE).^[21])
