Hi guys, I want to model the heat generation between two parts in Explicit. One of them ("fixed_part") is fixed with a pressure applied, the other one is a orbital sander and moves with a high frequency over the other surface. I attached some sketches to make the problem a bit clearer. fixed...

ok,sorry wrong... e.g. if you have the young's modulus is kg m^-1 s^-2 = kg m^-1 (1/3600)^-2 hour^-2 i hope this is right... basically you substitute second by 1/3600 h ...

well correct me if I am wrong, but since all those quantities do not contain time in their units, I think you don't have to change the units at all !?

thanks for all your help. unfortunately, I have no fortran-compiler @ work... I introduced the movement by implementing several rigid wires, turning them and connecting their movement to my assembly by making Tie-constraints. It may not be the most elegant way, but it seems to work for now. The...

Thanks for your response. I must say that I am not really sure that I understand what you mean. It must be clear, that the part should move on an orbital path, while the part should not rotate around its own axis. I attached a simple sketch that shall explain this a little bit better...

Hey guys, I currently have some problems figuring out how to implement the movement of a rectangular part/surface along a circular path. I cannot imagine to prescribe the motion with the conventional displacement/rotation- BCs, since the coordinates in the x-y- plane for instance would change...
