Prism layer
 

Hello friends,

Can I apply finer tetra mesh around boundraies rather than prism layer in unstructured mesh in icem?

Thank you

Hello Vav,

Yes, you can. There is a tutorial in the manual called Tetra Mesh in a Piston/Valve Assembly.

First Create Global Mesh parameters.
Mesh > Global Mesh Setup > Global Mesh Size
-Choose a Scale factor.
-Choose a max element size
-Enable Curvature/Proximity Based Refinement.
Ensure the Min Size is set to 1.
Next, Specify Volume Mesh parameters.
Mesh > Global Mesh Setup > Volume Meshing Parameters
-For Mesh Type, select Tetra/Mixed from the drop-down list.
-Select your mesh method (Robust (Octree))
-Click Define thin cuts. The Thin cuts dialog box opens.
Go from there.
