FEA applies to moving parts, e.g., https://docs.qblade.org/src/theory/structure/chrono/chrono.html.
Are you interested in how the machine deforms while you inject material that itself deforms? That means that you need to figure out the force coming from the injected material - this is a prerequisite for the deformation of the machine. Even if you have a FEA model of the machine, do you plan to come up in Chrono with the injected-material induced forces that are applied to this FEA model?

Thank you, Yes, I see the FEA support, but does that FEA apply to multibody? It seems all the examples are static. I'm specifically interested in testing, say, whether an injection molding machine will hold under a full cycle, which means a lot of frames and a lot of different forces, and certainly a lot of mesh. Okay I see this: chrono/src/demos/fea/demo_FEA_dynamics.cpp at main · projectchrono/chrono (github.com)<https://urldefense.com/v3/__https:/github.com/projectchrono/chrono/blob/main/src/demos/fea/demo_FEA_dynamics.cpp__;!!Mak6IKo!NQp999aRy30sMtZCVlCHnfM-q1WlDOpSYNeJfoVghoP7lMxG6hRZob3U2GWOWOSTJhRbVmimv-cPnl6WaWPRcUWndg$>, looks a little too basic, but I'll try to adapt it. Thanks.

Hello Chrono, Sorry if I'm missing the obvious, but is there soft body simulation? I'm looking through the PyChrono examples and it's empty. For example, I throw a polycarbonate brick against the wall and want to see it deform (elastically). Can Chrono do it?
