At this point, we have everything to describe solvers and create cases (simulation directories) from a solver.

We can then add API and commands to launch the simulations.

Launching simulation can be quite simple with OpenFOAM (for example only blockMesh and icoFoam) but it can also be more complex, for example (https://sedfoam.github.io/sedfoam/tutorials_laminar.html#wetvalanche2D):

blockMesh
snappyHexMesh -overwrite
extrudeMesh
# create the initial time folder
cp -r 0_org 200

# Initialize fields
mapFields -sourceTime 200 Reference1D
decomposePar
mpirun -np 18 sedFoam_rbgh -parallel > log&

Therefore, I guess we will need a kind of Makefile system. A question is do we use SnakeMake as in Snek5000? I guess SnakeMake is a bit too complex for what we need.

Then, there is the question of the API... Do we reproduce what has been done for Snek5000?

sim.make.exec("run_fg", nproc=18)
