Elmer is an open source multiphysical simulation software mainly developed by CSC. After it's open source publication in 2005, the use and development of Elmer has become international.
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).
CSC's offers additional consultation in the use of Elmer.
