Is it possible to (re)start a new simulation with the results of a previous simulation is input?
Hi all,
I am trying to run a simulation that consists of two parts. The first part is the shrinkage of an object inside a cylinder and this is the same for every simulation. In the second part this shrunken object is placed inside another object and for this step I would like to change the mesh, boundary conditions etc. in different simulations.
Is there a way to do the first part only once, and use the output of this part is input for the second part of the simulation? So, some kind of restart, only now you continue the simulation with different conditions each time.
Any help would be highly appreciated.
Kind regards,
Michelle

Are you using Optistruct?
It depends on the subcase types
You might be able to do this with submodelling, or local/global savedisp/getdisp, but some of this functionality is limited to linear static analysis types only
Thank you. I am using Radioss to do explicit simulations.
What I actually want is to perform 1 simulation and use the mesh and output of this simulation as a starting point for another simulation. Do you know if this is possible in Radioss?

Ah ok, for Radioss, you can try to use State file for this
The state file (.sta) can initialise the nodal geometry and stress/strain state on the mesh of the part (coming from a previous simulation)
