[ICEM] merge surface mesh

hadrien51 · October 17, 2012, 08:11

Hi Guys
I have a new problem.
I have a good stl and I want to merge some surface mesh with this stl to close the domain and use the total surface mesh to do a delaunay mesh. I send a picture.
I was looking for in edit mesh > merge nodes but I don't found nothing.
If you have a idea to do it ?
Thanks

You may be looking for the stitch edges command...

But an easier way to do it (assuming the purple surface is a mesh, or after you convert it to a mesh using Edit => Facets to Mesh) would be to close holes... Select one of the edges and flood fill (hot key "l") to select the others, then MMB.

Best regards,

Hi PSYMN
I try to close holes using edit mesh > repair mesh > Flood fill/make consistent
there is 2 option flood fill and make volume mesh ....
I suppose that I have to toggle on flood fill
you write "Select one of the edges and flood fill (hot key "l") to select the others, then MMB."
but if I select only flood fill I can't select nothing
and If I select both (flood fill and make volume....) I can select elements not edges and the key "i" doesn't work
and last question what means MMB ?
Sorry PSYMM, so many questions
thank a lots

I didn't mean to use the "Flood fill" command. you should use the "Repair => Mesh From Edges" Then select a single edge and then hit the hotkey "l" for flood fill. You could also pick flood fill from the selection tool box.

Best regards,

Simon
