Impact FEM Software
Encyclopedia
Impact is an open source finite element program suite which can be used to predict most dynamic events such as car crashes or metal sheet punch operations. They usually involve large deformations and high velocities.
Simulations are made on a virtual three dimensional model which can be created with a pre-processor or with the built-in Fembic language. Results are viewed in a post-processor.
Impact is designed to interface with the included pre- and postprocessor by default, but there are also interfaces available for more advanced pre-and postprocessors such as GiD or Gmsh
Gmsh
Gmsh is a finite element mesh generator developed by Christophe Geuzaine and Jean-François Remacle. Released under the GNU General Public License , Gmsh is free software. Gmsh contains 4 modules, for solving, geometry, meshing, and post-processing...
. Impact also has rudimentary support for Nastran file format
Nastran
NASTRAN is a finite element analysis program that was originally developed for NASA in the late 1960s under United States government funding for the Aerospace industry. The MacNeal-Schwendler Corporation was one of the principal and original developers of the public domain NASTRAN code...
