Draft: Setup to debug checkpointing with kOmegaSST

[MakisH]

Trying to create a setup to trigger and debug https://github.com/precice/openfoam-adapter/issues/158.

It currently does not trigger the checkpointing issue (OpenFOAM v2312), but instead diverges (the numerical setup is arbitrary, but it should already trigger the checkpointing issue before):

Courant Number mean: 51.1606 max: 4247.53
Time = 0.3

PIMPLE: iteration 1
diagonal:  Solving for rho, Initial residual = 0, Final residual = 0, No Iterations 0
DILUPBiCGStab:  Solving for Ux, Initial residual = 0.802428, Final residual = 3.49139e-07, No Iterations 36
DILUPBiCGStab:  Solving for Uy, Initial residual = 0.779756, Final residual = 7.00548e-08, No Iterations 40
DILUPBiCGStab:  Solving for h, Initial residual = 0.868425, Final residual = 7.90218e-07, No Iterations 35
DICPCG:  Solving for p_rgh, Initial residual = 0.841614, Final residual = 0.00718705, No Iterations 70

time step continuity errors : sum local = 4.42713, global = -3.13549, cumulative = -3.14201
