Overlapped lines bothering meshing
I'm modelling a layered cube with SOLID186 in Mechanical APDL. Each layer has controlled gaps (1mm voids) in specific positions. Because of that, my geometry model ends up with coincident lines with different length, not being able to use NUMMRG,ALL to merge them before meshing. If I didn't have those gaps, I would just use NUMMRG,ALL command to merge coincident KP,lines, etc. and my mapped meshing would work great.
I'm creating geometry with volumes using BLOC4 command. Each layer is composed of two blocs. Here are some pictures:
The regions like the one marked in red have 3 coincident lines, each of different length. Is there an "easy" way or command to be able to merge or reppair this problem, instead of having to do a more complicate geometry modelling?
Thanks in advance.
