The main factor impacting the accuracy of Autodesk Moldflow analyses is whether the model topology is correct or not. CAD models often contain modeling errors that are not readily apparent in the CAD model, but which adversely affect the quality of a mesh. These modeling errors become apparent in the mesh.
Ensure that your model does not contain any of the following typical issues on Surface meshes:
Use the Mesh Statistics report to see at a glance if your model has such problems. If any, use the relevant specific diagnostic tools, described in this section, to locate these errors in the mesh.
