[ANSYS Meshing] Meshing 25 micrometers gap

Mr.H · July 30, 2013, 05:20

Hi,

I'm trying to create a mesh with inflation for my case, but I have a trouble with that I have a tube with diameter 57 mm and inside of the tube I have a plate which is rotated 8 degrees from axes of the tube and has a elliptic shape with 2a=56,910mm and 2b=56,984mm so it create only about 25 micrometers gap between plate and tube and i have a problem with meshing this room. I can't use any inflation. I guess it is because of the small distence but I'm not sure.

Here is the warning message when I try to create a mesh with inflation:

Patch-conforming tetrahedron mesh failed possibly because of bad boundary or inflation mesh.

Can anyone help me?

Thx

Can you post pictures from your case?
