To calculate linearized stress, define a line (using the end nodes) across the section where the calculation is desired, Figure 22.

Ensure NASTRAN structural and model are open & running Make sure .
NOTE: The models must be in the same location in space and have the same dimensions within very small tolerances.
The Ansys preference is not complete for this type of translation, so this is a somewhat convoluted process.
Included are some suggestions to aid convergence of transient analysis models which are large (greater than 6,000 nodes), contain advection, and are having problems converging with the adaptive time step defaults.
If the model is now convergent but still takes unreasonably long to converge either because the time steps are too small or it requires too many iterations per time step then there is another parameter which may be useful.
