Create mesh with triangular block #78
Description
I would like to create a blockMeshDict with classy_blocks with a triangular block. Such blocks are usually used for wedges, but they also seem to work for normal or in my case 2D cases.
I created a blockMeshDict by hand which includes such a block (see below).
The block 0 is the triangular block (the first in the blockMeshDict).
I have not find a way to specify such a block in classy_blocks. classy_blocks.Face requires 4 points which seemingly can only be given as cooridnates and not as a list of Points. Is there a way around this? E.g. by specify/create the block directly from a list of Points (not coordinates)?
The purpose of this would be to create blocks for prism layers around a body. By this way, the refinement for the prism layer is not needed to be carried around through the whole fluid domain.
