Reply To: Restart (Switch Implicit => Explicit )

Is it possible to perform stress simulation for a material with viscous properties (mat 269 or 318 or “external” models of materials from PolyUmod) using a full restart?

Step 1 – static loading – implicit solver
Step 2 – dynamic loading – explicit solver

If anyone has such an example – I will be glad to get acquainted with such models.

I tried to perform stress simulation using "external" material models from PolyUmod  using a full restart , unfortunately my attempts were not successful.

The reason is that LS-DYNA could not read the calculation results from the first (static) step, for parts using the above materials.
