Impact Finite Element Program
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. It is written in Java
.
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
. Impact also has rudimentary support for Nastran
file format.
Development started as a free and simple alternative to the advanced commercial Finite Element codes available made by a group of colaborating developers, and now is made by a team of volunteers from all over the world with the aim of creating a clean and compact program which is simple to understand and use.
Open source
The term open source describes practices in production and development that promote access to the end product's source materials. Some consider open source a philosophy, others consider it a pragmatic methodology...

Java (programming language)
Java is a programming language originally developed by James Gosling at Sun Microsystems and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities...
