Example Impact using shell elements

waluyo

Could anyone provide a simple example of impact simulation (ccx solver) for shell elements. The problem might be crushing thin cylinder (shell elements) on a wall (plate). The cylinder has an initial velocity.

Here you go.

Initial velocity (*INITIAL CONDITIONS) doesn't seem to work for shells - only solids from what I can tell. So I used a force to accelerate the object then released the force before impact so it would have a predictable initial velocity.

Is explicit time stepping available?

The CCX manual says it has an explicit option (*DYNAMIC,EXPLICIT) but I haven't been able to get it to solve properly.
