Abstract

We propose a high performance computingstrategy (HPC) to simulate the deformation of a solidbody through time as a consequence of the internalforces provoked by its temperature change, using theFinite Element Method (FEM). The program finds asolution of a multi-physics problem, solving the heatdiffusion problem and the linear strain problem forhomogeneous solids at each time step, exchanginginformation between both solutions to simulate thematerial distortion. The HPC strategy approachparallelizes vector and matrix operations as well assystem equation solvers. The tests were realized overa model simulating a car braking system (a rotating diskvelocity decreased by friction). Then we performed aquantitative analysis of stress, strain and temperature insome points of the geometry, and a qualitative analysisto show some visualizations of the simulation.
