A finite addition of matter elements method for modeling and solution of an SLM thermal problem by a multiscale method

In this article, we are interested in flexible modeling and performing solution of transient thermal selective laser melting problems. For this, first introduce a finite addition matter elements method (FAMEM) to generate any wished sequence problems, defined additively constructed domains. Second, use the multiscale Arlequin frame-work develop three-level weak-strong formulation each problem sequence. Two patches used latter localize steepest gradients nonlinear phase-change phenomena, allowing for fine local approximations localized nonlinearity treatment by an algorithm develop. These identified via representative mono-domain problem. The is also solved with our comparison solutions respective performances both approaches. Moreover, two dimensional tests consisting creation 316 L stainless steel wall AlSi10Mg layers, carried out further enlighten global approach position it respect literature.
