meshing doesn't respect geometry [RESOLU]
 
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.

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.

De rien, bon courage ;)
