Good Morning!
As the title says, I want to use that solver but using my model from enGrids. I have achieved to make it work but creating the model from blockMeshDict "by hand" (I attach it).
Do you know what files should I change/add/delete for my purpose?

I have been searching for some information about it. The only thing I found is this tutorial, but there is no explanation and, from my point of view, the topoSetDict is wrong, because it belongs to other tutorial (heatexchanger), so it doesn't help too much.

Thank you in advance!
