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.
