  1. Hi, I am trying a simple impact analysis like radioss example 26 ruptured plate ( I am not interested in the rupture, just want to try an impact problem). I am using a soft non linear material M36_PLAS_TAB with a stress strain curve (E=8Mpa,nu=0.42,rho=1.412e-6Mg) and fixing the whole bottom surface. I used the volume tetra mesh to mesh my disk. ( I am using solid elements instead of shells as a basis for a more complex problem I am working on) The model was working fine with linear elastic materials... I read a few posts about this problem. There it was suggested to use a really thin linear elastic surface on top. And to change the element formulation. Could you please elaborate more in detail the steps to overcome this problem? Thanks!
  2. Hi everybody. Is possible to create a component with different thickness along of its length, for example like a wedge? I want to create a component with variable thick but progressively without a drastic change between sections of the component. Thanks for your answers.
