Cannot export a TRI3 type mesh

Coreform Cubit Importing/Exporting
#1

Hi all,

I’m getting a problem with exporting surface memsh in CUBIT.
I think by default surface mesh is a shell type. I tried to force it by a tri mesh type and export it but somehow CUBIT didn’t do that. (I tried in both 3D and 2D, but it didn’t help).
Could someone give me some comments about this?
Any helps will be appreciated.

Thanks in advance,
Loi

I’d like to describe more detail about this problem.
For example, I have this code:

[code]rese
brick x 1
volume all scheme tetmesh
mesh vol all

block 1 surf 1
block 1 element type TRISHELL3
export mesh “face1.exo” dimension 3 block all overwrite
delete block all

block 1 surf 1
block 1 element type TRI3
export mesh “face2.exo” dimension 3 block all overwrite
delete block all

block 1 surf 1
block 1 element type TRI3
export mesh “face3.exo” dimension 2 block all overwrite
delete block all[/code]

Then I will have 3 mesh files. When I imported these files into CUBIT again, I saw their type all are TRISHELL3. And when I imported them into Paraview, I saw their type all are TRI3.
I guess, the type of these file are TRI3 but each element in these meshes has 5 sides because it must be being written out as a TRISHELL3 which has a “top” and “bottom” surface as well.
So could someone show me how to export a consistent TRI3 mesh please?

Thanks,
Loi
