Hi,
I'm new to abaqus solver and I'm working on a very simple model of impact to study the inp abq code for dynamic and explicit analysis.
Simulation is completed but no motion seems to happen in the odb file. I'm not sure what is making it rigid. Impact should occur between a cylinder and a rigid plate.
Could anyone have a look on that? Or does anyone have a good tutorial file?
Thank you very much
