A predictive software relies on exact physical and numerical models. The most important aspect is the correct modelling of the thermal conditions. Almost all modifications of process parameters have a direct influence on heat conduction, the coupling of the energy source or heat sinks by e.g. heat radiation or evaporation. Furthermore, many material parameters are temperature dependent and sensitive to a correct model. During melting a melt pool evolves, whose dynamics are mainly covered by capillarity, wetting, Marangoni convection and gravity. The temperature gradient and the solidification velocity mainly influence the final microstructure while solidification.
