Many particle simulations today rely on spherical or analytical particle shape descriptions. They find non-spherical, triangulated particle models computationally infeasible due to expensive collision detections. We propose a hybrid collision detecti...

A Contact Detection Code using Triangles for Non-Spherical Particle Simulations (2016)
Conference Proceeding
Krestenitis, K., Weinzierl, T., & Koziara, T. (2016). A Contact Detection Code using Triangles for Non-Spherical Particle Simulations. In Proceedings of the 24th Conference on Computational Mechanics (ACME-2016): 31 March - 01 April 2016, Cardiff University, Cardiff (227-230)

We present a novel DEM (discrete element method) code with explicit time stepping. DEM codes simulate billions of small particles that interact with each other primarily through collisions. Different to state-of-the-art codes, we rely on triangulated... Read More about A Contact Detection Code using Triangles for Non-Spherical Particle Simulations.

Calculating the minimum distance between triangles on SIMD Hardware (2015)
Conference Proceeding
Krestenitis, K., Koziara, T., Gil, A., & Sevilla, R. (2015). Calculating the minimum distance between triangles on SIMD Hardware. In Proceedings of the 23rd Conference on Computational Mechanics (ACME-UK 2015) : 8 - 10 April 2015, Swansea University, Swansea (55-58)

This paper presents an investigation into calculating the minimum distance between two 3D triangles on SIMD hardware. We formulate the problem as constrained minimization and apply a quasi-Newton method to solve its multiple instances simultaneously...
