Impact is a finite element program for simulation of dynamic events such as car crashes or other large deformation events. It is kept very simple to make it intuitive to use and easy to change and extend. The program includes a NURBS based pre-processor for modelling, a solver with editor, a post-processor, and a graph plotter for results viewing. Impact also interfaces with several other programs, such as Nastran and Gmsh.
This release finally allows groups to be usable in the preprocessor. There is also a bugfix for the NASTRAN file import filter.
