How to solve mesh artifacts, obtain reaction forces and contact penalty

  Hi,
  
  When using solid elements to mesh each of the 12 layers of composite I am simulating that is subjected to a low-velocity impact, in section view the mesh goes crazy like in the picture. It almost disappears when impacted, but this only happens when using this mesh element. How can I solve this?
  
  Also, I want to obtain the impact force caused by the impactor to then plot a Force vs Displacement graph. What is the best method? I have tried bndout but it says "file has no information to be found", and spcforc has forces = 0.
  
  As for the contact, my impactor is visually surpassing the outmost layer. Is there any setting to solve this?
  
  Thanks!

  Hi,
  I'll talk about the contact penetration problem.
  To decrease pentration, increase contact stiffness.
