Can I make SECTIONS in TETRA MESH ?
Altair EmployeeHello,
I want to make a model including a cylindrical shell (gray) and two rods (blue).
I made a set of tetramesh in HyperMesh.
And I would save it as .inp and export to ABAQUS to conduct CAE.
I want to make the gray section steel , and make the blue section titanium. So, I have to divide the model.
I may assign materials in ABAQUS, but ABAQUS doesn't seem to support dividing objects.
How can I divide the tetra-meshed model into two groups?
Thanks.

Hi,
If all tetras are coming in same component then using organize command you can move element to other components.(Tools Page - Organize)

Altair EmployeeThank you Rahul.
But, how can I specify the blue region only?
I hope in your case all elements would have generated in one component.Since you have divided blue & grey section as separate component you can organize it in separate component.If find difficulty.please share your model.

Altair EmployeeI upload two files.
sss.step and mesh_file.hm .
sss is just the model
and mesh_file is the tetrameshed one.
Thanks.
Altair EmployeeThank you so much, Rahul !!!
Altair EmployeePlus, can I ask you an easy question more?
With the file sss,
I want to make the mesh size of the rods small (say, size=1)
and
I want to make the mesh size of the cylinder large (say, size=10)
Is the interactive mode of 2d automesh the only way I can use ? by clicking one by one ?
You should have two separate components then mesh with different size in 3d page: volume tetra.
Make sure you should have two diffrent volume.

Altair EmployeeWell , I cant make separate components before making 3d tetramesh.
How can I deal with it ?
Hope it would be easy in CAD software.In Hm you can do that but time consuming.

Have a look at my test.

Well,
what I want is to assign tetra-meshes into two groups.
Group 1 : cylindrical shell without the rods.
Group 2 : two rods
Thanks.
