[FAQ]

The program still uses the thermal solver’s general thermal strain algorithm to calculate the anisotropic thermal strain values based on the scan pattern but it does not involve the main thermal analysis of the thermal solver. So, the only thing the thermal solver does in a scan pattern simulation is it uses the anisotropic strains calculated in each layer given by the following formulae: Parallel Strain = 1.5*SSF*YS/E => parallel to the scan vector Perpendicular Strain = 0.5*SSF*YS/E => perpendicular to the scan vector Z-Strain = 1*SSF*YS/E => in the z-direction and accumulates all the nodal values at each layer. Due to this reason, one will observe that the thermal solvers status changes to “Finished” quickly when solving scan pattern simulations.
