[ANSYS Meshing] body of influence vs. contact region

Diger · July 14, 2016, 16:52

I'm using body of influence for the meshing from one region to another, but everytime I set up the element size/body of influence setting the contact region between those two regions changes into a question mark...
Does anyone know which problem could arise here?

edit: maybe to clarify. As soon as I select the body of influence and hit select the contact regions of this body of influence become a question mark.

put some pics
delete all auto generated contacts and create contacts manually

Thx for ur reply. I sorted this problem...Sorry not to mention: The issue was that I didnt use multibody for my parts an thats why many contact regions arose. With multi-body in DM this issue does not arise. Though still now I have another problem instead. The body of influence chosen is not considered in the mesh. It's gone and I have a gap in my body :-/
U want some pics about it or is it clear enough?

pics are equivalent of 1000 words.
SO always post pics and describe the problem.

Did you solve this problem? Basically I want to use Body of Influence, but I also want to keep the "body". Is this even possible?

Unfortunately not :-(
I guess I "solved" it by splitting my body into a couple of parts and choosing different element sizes for each of them.
But if you find a solution I'll be happy if you share it :-)
