Steady state numerical calculation of the melt-pool shape

Abstract

A two dimensional steady-state melting problem is numerically simulated. This task arose during the Selective laser melting (SLM) additive process technology modelling project. Initial problem is formation of residual stresses and, as a consequence, appearance of accumulated deformations (inherent strains) and distortion of final production shape. As solution of this initial problem I suggest development of own appropriate software tool. Development process was divided on 5 stages. Stage 1 is to model the geometric size of the molten bath. A comparison of the results obtained with in OpenFOAM (laserConvBC) and results from similar article.
