Restart option for Parallel CPUs

[CS54]

I use a university cluster for my simulations. I would like to use the restart option to not repeat the initial steps in my simulation. However, the .res file does not recognize my restart simulations. If I use a single CPU, it works. But if I increase the CPU number, the restart option does not work.



Is there any suggestion for this?

 

[FEA way]

Is it Abaqus/Explicit analysis ?

 

[CS54]

Yes, it is Abaqus Explicit. I have been using the same number of CPUs for both the main model and the restart model.

Is there any particular error message ?

Check the documentation chapter "Parallel execution in Abaqus/Explicit", paragraph "Restart". There are some special considerations when using restart with domain-level parallelization.

I checked that. It says you should be using an equal amount of CPUs for both models. It actually works on my personal computer. However, it does not generate any abaqus or error files in the cluster. I got in touch with the university staff about this issue. If anything comes up, I will post it here.
