I have a pin by pin (ONLY have 7 pins in total) hexagonal benchmark problem, the outer boundary conditon is reflective. My question is how to set boundary condition for this problem?
I got the same problem and I’ve tried to apply your suggestion. However, some of the surfaces defining the outer boundary “cuts” the domain, resulting in unwanted reflection inside the domain.
For example, given @pitch as the pitch of a single hexagon, supposing we’re looking at a figure in the xy plane, I can easily define a YPlane at 1.5@pitch in order to bound the top part of the domain. On the other hand, if I want to bound the top of the 2 green haxagons, I would need to define a YPlane at @pitch, but this plane would cut the top indingo hexagon, causing unwanted reflection in this region.
