[ICEM] Mesh Over Cylinder

AshwaniAssam · August 20, 2015, 06:14

Dear all,

Can anyone help me in unstructured meshing over cylinder. I have seen the tutorial where we make one in 2D and then extrude it in 3D. But I am trying to mesh in 3D geometry directly. But in the z direction (i.e. normal to cylinder cross-sectional surface) I want only one cell thickness.

Is there any way, apart from blocking.

Please help.

with regards,
Ashwani

Hi,

Why do you use the structure mesh?

You can block the computational domain. It is easy.

I do it in Gambit. Please see the attached file.

Best,

Thanks for your reply.

I need to validate our unstructured code on non-hexagonal cell. By using one cell direction, I am able to compute 2D cases using 3D meshes with relatively less number of cells.

I needed it in ICEM for this is available meshing tools for us.
So, if it can be done in icem - how to fix number of layer in one direction.
