finally I could find one predefined thermoset polymer in the material database of SWX Plastics.
It is a kind of silicone: the WACKER/SiliconesElastosil LR 3003/70.
When you go into the polymer's product manager with the edit icon, you can check on the "Viscosity" tab, whether it is a thermoplastic or a thermoset polymer.
If you choose a thermoset from the database the fill settings will be a little bit changed.
"Reactive Control Type" is displayed as a sign, that we are not facing with a single injection molding process in this case.
If we define the right filling properties we have a good chance to simulate a reactive molding process.
This way we will get extra results in the flow results list of our study.
Unfortunately usable thermoset polymer presets technically don't exist in the material database of SWx Plastics.
Of course, for me it is a question, how well can the curing model works in the case of a PUR f.e.?
I hope some discussions could start in this topic with your experiences.
