Check whether an MPI 6.0 or later version of Autodesk Simulation Moldflow Insight 3D Warp has been run in order to use this feature, or re-run the whole analysis sequence again. Check whether mesh aggregation is used for 3D Warp; the initial stress cannot be produced for aggregated mesh. MPI 6.1, and later versions of the Autodesk Simulation Moldflow Insight interface program build initial stress based on Fill+Pack results, so it may take some minutes.
