Adaptive Finite Element Modelling of Welding Processes

We describe the ModFEM_met service within the PL-Grid Infrastructure, designed to model welding processes using adaptive finite element method FEM. The code aims at utilizing modern computing environments to produce high quality results for large scale problems. It exploits different forms of parallelism to improve the performance of simulations. The program uses a three-dimensional model of laser welding for materials with different chemical compositions.
