Hi,
I'm trying to mesh a 3D geometry. I have defined differents parts (each surface are in a part).

I have defined mesh caracteristics on the surface and I'm using the "Volume meshing" tools.

There are some problems at the intersection of differentes surfaces.
I don't know which parameters can resolve this problem.

regards
Alex

Do you have curves between your surfaces?
Before meshing, use the tool "build topology". It creates curves between surfaces with different colors : red when curves are shared with 2 surfaces, blue when curves are shared with 3 surfaces, yellow when curves are shared with only 1 surface.

Thanks for your answer but I already have curve between surfaces (red curves after use the tool "build topology").

Try to play with the edge criterion option (Global mesh setup -> Volume mesh).
Reduce it to 0.1 first, and see how it works.

thanks a lot!
I have good intersections with an edge criterion = 0.1.
