Problem in repeating sd7003 sim with PyFR v 1.12.1.1

It seems that setting

[backend-openmp]
gimmik-max-nnz = 8192

as suggested in https://pyfr.discourse.group/t/keyerror-on-3d-case-running-with-wsl-ubuntu-openmp/404/9, made the simulation ongoing.

What I really cannot understand is the reason: why the cuda-backend would not require to enlarge the number of non-zero elements in a constant matrix for Gimmik?

Any hints would be greatly appreciated!

Best,
Federico Cipolletta.
