Parallel Processing Strategy for Solving the Thermal-Mechanical Coupled Problem Applied to a 4D System using the Finite Element Method
We propose a high performance computing strategy (HPC) to simulate the deformation of a solid body through time as a consequence of the internal forces provoked by its temperature change, using the Finite Element Method (FEM). The program finds a solution of a multi-physics problem, solving the heat diffusion problem and the linear strain problem for homogeneous solids at each time step, exchanging information between both solutions to simulate the material distortion. The HPC strategy approach parallelizes vector and matrix operations as well as system equation solvers. The tests were realized over a model simulating a car braking system (a rotating disk velocity decreased by friction). Then we performed a quantitative analysis of stress, strain and temperature in some points of the geometry, and a qualitative analysis to show some visualizations of the simulation.
