Impact is an explicit Finite Element Program Suite which simulates dynamic impact events. It has a range of elements, contact handling and different material laws. Models can be created, solved and analyzed with the included pre- and postprocessor. Impact is based on an Explicit Time stepping algorithm. These kind of codes are used to simulate dynamic phenomena such as car crashes and similar, usually involving large deformations. Features Nonlinear simulation with contact and nonlinear material Support elastic, elastoplastic and thermoelastoplastic materials Integrated environment, preprocessor - processor (solver) - postprocessor Support GiD preprocessor via Impact interface module
