This is the official source code repository for the Elmer FEM software suite.
Elmer is a finite element software for numerical solution of partial differential equations. Elmer is capable of handling any number of equations and is therefore ideally suited for the simulation of multiphysical problems. It includes models, for example, of structural mechanics, fluid dynamics, heat transfer and electromagnetics. Users can also write their own equations that can be dynamically linked with the main program.
Elmer consists of several parts. The most important ones are ElmerSolver the finite element solver, ElmerGUI the graphical user interface, and ElmerGrid the mesh creation and manipulation tool. Also a visualization tool, ElmerPost, is included in the package but it is no longer developed.
