Hi Gid Team
I frequently have to do an analysis using geometry of an assembly
imported from CAD via an iges model (for example). This normally
requires huge amounts of post processing to ensure that I have only one
common surface between mating parts by splitting surfaces & volumes etc
so the mesh matches across common boundaries. I have attached a simple
example of a rod passing through an annular ring where the OD of the rod
& the ID of the ring are identical, is there a simple way of making the
meshes of the 2 parts match over their common surfaces?

Dear Mark,
In the example you sent us, I recomend you to split the surfaces 1 and 2
using the contour lines of surface 7, and then you should collapse the
surfaces which are "in the same place" in the space.
Kind regards,
ABEL

Hi Abel
Thanks for the reply, what you suggest is what I would normally do but it requires lots of work for more complex geometry ;-(
What I would like is to have a setting which automatically makes the meshes match across common boundaries.
