fedarduino is on a distinguished road
Hello everybody,

I am new to OpenFOAM. I am trying to simulate a casting filling process by using the interFOAM solver. I imported and meshed my geometry through Salome (using then the IdeasUnvToFoam tool) and ran it.
Everything looks fine, despite the fact that, regardless of the values of deltaT, maxCo or maxAlphaCo I use in the controlDict, the simulation is really slow (with deltaT around 10^-5) and I cannot get any results out of it.

Do you have any hints about how to solve this problem?

If needed I can upload my .unv mesh file as well. I attach here my controlDict file.

Thank you in advance for your help!!
