Unmatching nodes

Postby jackcronkite » Tue Feb 14, 2012 6:18 pm

I am creating a 3D mesh. The mesh consists of 3 adjacent blocks. While trying to mesh it, I am getting nodes along shared edges that do not match both sides of the mesh of adjacent blocks. I am probably doing this all wrong but don't know how to proceed. Any help is appreciated. Attached is the journal file I created. In the end I need a mesh that does not have repetitive nodes on shared edges/surfaces.

You might first want to delete the surfaces used to create volumes 17, 18, and 19. This just cleans things up a bit, but isn't necessary. Then, you should "merge all" to merge the surfaces where the blocks touch to make one shared surface. When you mesh the volumes they will share the mesh. Try this in your journal file:


create volume surface 4 7 8 9 10 11 heal keep
# Volume Block 3
create volume surface 9 12 13 14 15 16 heal keep
# Create meshes
delete volume all except 17 18 19
merge all
mesh volume all
