It has also been pointed out to me that by going below 350mm/s, if you don?t simultaneously lower laser power (below the minimum limit of 50W), then the meltpool will grow too large for the solution domain, throwing an error or making the solution invalid. nBut lowering the 50W limit is not necessarily the solution to this, because if we go slower and with less power, then we have a lower cooling rate which will make our material property assumptions less accurate, which speaks to the first comments I made earlier.n
