Multi-level finite elements of high-order for the simulation of melt pool sizes and cooling rates in metal additive manufacturing
Published: Jan 1, 2018
Abstract
The presentation addresses the numerical modelling of the benchmark AMB2018-02 where we take upon the challenge of verifying the melt pool geometry (CHAL-AMB2018-02-MP) and the cooling rate (CHAL-AMB2018-02-CR). We employ a variant of the numerical model presented in [1] and extend it to hierarchical B-Splines [2]. The principal idea is to use high-order refinements to resolve the region around the boundary of the weld pool with high accuracy....
