  I am using the explicit dynamics to model the large deformation of a surface model. The material is based on Mooney-Rivlin 5 Parameters model, as shown bellow:
  
  When I start the solving process, it just stops immediately with problem "Material with invalid equation of state assigned to Part 1.". However, when i use static mechanical to solve the problem, there is no problem. I am wondering whether this model is applicable for surface body in explicit dynamics? Thanks,

  The user manual (explicit dynamics) says that Hyperelastic material only work with 3D parts not with surface bodies.
