Volumetric shrinkage too high: Mesh too coarse?

Question asked by Eg Gloo on May 7, 2016

Hi all


I'm running the Plastics add-in on a small part:

The material chosen is POM using a P20 mould. All other settings are set to auto. However, the shrinkage I get over much of the part is around 13%:

This is the mesh view:

Does anyone know why shrinkage is so high? Could it be the large mesh size? For instance, the round cuts are modelled as square cuts:

Is there a way to refine the mesh?


Any thought appreciated.
