Elmer is an open source multiphysical simulation software mainly developed by CSC - IT Center for Science (CSC). Elmer development was started as national collaboration with Finnish Universities, research institutes and industry. After it's open source publication, the use and development of Elmer has become largely international.

Elmer includes physical models of fluid dynamics, structural mechanics, electromagnetics, heat transfer and acoustics, and beyond. These are described by partial differential equations which Elmer solves by the Finite Element Method (FEM). Elmer supports parallel computing. For many problems good scalability over thousands of cores is reached. 

The development of Elmer has been pushed forward by numerous R&D projects where the capabilities have been gradually extended. Currently the most notable use fields are computational glaciology and computational electromagnetics. Elmer with its ice-related modules, known as Elmer/Ice, has a large international community and dedicated portal, see elmerice.elmerfem.org. In electromagnetics Elmer team is part of The Centre of Excellence in High-Speed Electromechanical Energy Conversion Systems (HiECSs), www.aalto.fi/en/hiecs. There are also many other niche areas where Elmer offers competitive solutions, for example in fluid-structure interaction, and thermal problems involving thermal radiation. 

These pages are intended to give basic information on the Elmer software. The content of the pages is rather static, For more concurrent information visit the community portal at http://www.elmerfem.org.
