In order to use the "Importing Results from SolidWorks Plastics" functionality in SolidWorks Simulation, a .POE file must first be exported from SolidWorks Plastics. Here are the specific setting requirements to allow export of a .POE file in SolidWorks Plastics:

Mesh: Solid > Manual > Tetrahedral Mesh > Hybrid or Tetrahedral of a Part with a single solid body

Material: Isotropic (in Polymer-Material Parameters, the Parallel direction values must be equal to the Normal direction values for: Elastics Modulus, Poisson’s Ratio, and the Thermal Expansion Coefficient)

Run: Flow + Pack analysis must be completed
