I tried to run step-40 with 52M DOFs on 32 processors. I am using
*GridGenerator::subdivided_hyper_rectangle *to create a mesh with
5000*5000 elements. I have a single cycle in my simulation. However, I
am running into some memory issues.
I am getting the following error: *Running with PETSc on 32 MPI

*Cycle 0:

I tried with 40 processors (125 GB RAM) but I am getting the same error.
I'm pretty sure you run out of memory. You need a smaller problem, a
larger machine, or both.
