Can you add some more details?

Fixed!

With #1696 we are down to the following groups in restart files: ``` [drwells@mitral nodes.00016]$ h5dump -H proc.00000 | grep GROUP | grep CURRENT | sort -u GROUP "IBFEMethod::lagrangian_workload##INSStaggeredHierarchyIntegrator::CURRENT" {...

That patch also introduced a bug in a corner-case: if we want to regrid immediately after restarting then the vorticity is not available.

Good to know. We need to move some of the code in that function somewhere else, since the INS classes do some extra initialization there which will otherwise never occur.

Is this ready for review again?

I haven't had time to review it. Lets tackle this one next week.

I compiled the Fortran code with warnings enabled - we should turn those on in the CI (see #1705).

Want to add a test?
