In WB-Mechanical, we use a Lumped Layered approach to simulate the AM material deposition. You can read more about this in the Additive Manufacturing Analysis Guide. load applied is temperature, not heat, and not at the local level (i.e. laser path). Below is an illustration of the process. The assumption is that the process parameters for the build have been set appropriately so that (1) the developed temperature is always at or above melt (no lack of fusion) and (2) the developed temperature does not greatly exceed melt (no keyholing).nn
