Femap

FE model created with Femap

Femap is a graphic pre- / post-processor based on the finite element method (FEM) for the creation of FE models and the evaluation of calculation results. In combination with the optional FEM solver NX Nastran, this results in a CAD-neutral program for the simulation of static, dynamic, thermal and non-linear processes.

description

This software is mainly used by designers and calculation engineers, since finite element calculations are now an integral part of product development and the verification of structures. Femap is most widespread in machine and vehicle construction, the aerospace industry, shipbuilding and offshore. The range of applications is broad and, in combination with the integrated Nastran solver, covers in particular the areas of linear statics, non-linearities , dynamics and thermal. Femap can exchange data with all common CAD systems (import and export of data). Based on the implemented Parasolid core, the user is able to edit the imported data or create his own geometries in 1D, 2D and 3D. Extensive geometry functions enable z. B. the creation of mid-surface models or the idealization or simplification of CAD models tailored to the individual requirements of the user. Import and export interfaces to various other FEM systems are also part of it, as is an API interface. Femap is only available for Windows 64-bit. The licensor of the software is Siemens PLM . Femap is also used by providers of other FEM programs ( ADINA , NEI Nastran) as a pre / post processor. Licensing takes place either via USB dongle (node-locked, not computer-bound), FlexLM (floating) or activation code (online subscription, computer-bound). Trial versions without node limitation with the calculation scope of the basic version including the dynamic module are available for immediate download. The software is subject to US export regulations.

history

• 1985: The first Femap version is published by the Exton- based company ESP by George Rudy and Mark Sherman as pre- / post-processor for Nastran. Initially available for Unix and Windows , Femap quickly spread to the US aerospace industry
• Nastran for Windows, offered by MSC Software from 1995 to 2006, consisted of Femap and the integrated Nastran Solver
• 1999: ESP is taken over by SDRC .
• 2001: UGS takes over SDRC
• 2006: Nastran for Windows disappears from the market
• 2007: Siemens PLM takes over UGS
• 2020: the current Femap version is 2020.1
