In finite element analysis, traditionally we define the geometry at the start of the analysis and assume that while it may deform, the amount of material stays the same. For additive manufacturing, this is clearly not the case: material is continuously added. If we look at the thermal aspects of things, we also see a constantly changing problem: over time heat is added at different points in space; and the outer surface, where heat loss occurs, changes over time. Specific capabilities are therefore needed to efficiently set-up the simulation of problems that continuously change, such as the additive manufacturing process.
