Is there any way to directly access the OpenFOAM BlockMesh grid generation within SimScale or does it have to be done outside SimScale and then uploaded as the mesh? If this is not available, would it be possible to allow this form of grid generation in the future?
That’s not possible except doing it directly with OF externally. We are using SnappyHexMesh at the moment as you might have guessed. For feature requests I would highly encourage you to post them right into this section here: Vote For Features.
Let me know if you have any other questions.
