Tamaas — A high-performance library for periodic rough surface contact
Tamaas (from تماس meaning “contact” in Arabic and 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. doi: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 aimed at researchers and practitioners wishing to compute realistic contact solutions for the study of interface phenomena.
