Description
Tamaas (from تماس meaning "contact" in Farsi) is a high-performance rough-surface periodic contact code based on boundary and volume integral equations. The clever mathematical formulation of the underlying numerical methods (see e.g. 10.1007/s00466-017-1392-5 and arXiv:1811.11558) allows the use of the fast-Fourier Transform, a great help in achieving peak performance: Tamaas is consistently two orders of magnitude faster (and lighter) than traditional FEM!
Tamaas is being actively developed on https://c4science.ch/tag/tamaas/ by the Computational Solid Mechanics Laboratory (LSMS) at École Polytechnique Fédérale de Lausanne, and is freely available under the terms of the GNU Affero General Public License.
