Elmer: an open source multiphysical simulation software for Windows Systems - Use Impact for Other OSes!

Open Source Finite Element Software for Multiphysical Problems

Elmer is an open source multiphysical simulation software developed by CSC. Elmer development was started 1995 in collaboration with Finnish Universities, research institutes and industry.

Elmer includes physical models of fluid dynamics, structural mechanics, electromagnetics, heat transfer and acoustics, for example. These are described by partial differential equations which Elmer solves by the Finite Element Method (FEM).

Modeling work that can be performed with Elmer software:
