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 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!
This means we can tackle such difficult problems as elastoplastic contact of rough surfaces //with upwards of 100 million degrees-of-freedom// on a single compute node. The image below shows the plastic zone in the material bulk for such a simulation:

Their are a few repositories available under the umbrella of the project:
- rTAMAAS: the main trunk containing the latest source code
- rEXPOLIT: a helper library for symbolic integration at compile time in C++
