restrictions with rigid bodies in flexible dynamic simulations

restrictions with rigid bodies in flexible dynamic simulations

Hi everyone,

First of all, I'm working in Workbench...

I'm modelling an impact where I am colliding a 3000lb shock test hammer with a 4000+ assembly.  I am not concerned with the deformation of resonance of the hammer, but I have modelled it anyway.  I modelled it to reflect its weight and the impact surface geometry.  

If I set the hammer to be rigid, i cannot set a valid contact point with the assembly.  If I model the hammer to be flexible, I would imagine it will add to the computation time.  Do you have any suggestions for such a simple dilemma?  

Instead of modeling the hammer, I could assign a point mass of 3000lb, but what would I create for its geometry?  With this method, I would run into the same problem, no?
