Cut Cell Meshing
 
Hi

What are the advantages and disadvantages of using the cut cell meshing feature in ANSYS Meshing?

PSYMN August 3, 2011 10:16

The main advantage is that you can easily (push button mesher) get a predominantly hexa mesh with inflation layers to capture your viscous boundary effects. Studies have shown that the solver likes the mesh and converges more quickly and accurately than with tetra/prism meshes.

The main disadvantage is that it only works with the Fluent solver. CFX, ANSYS Mechanical, AUTODYN, etc. do not support the hanging nodes or polygons that come with cutcel mesh.

This mesher is relatively new to ANSYS Meshing and has been under heavy development the past few years, so if you have an old version, it may not yet support baffles or narrow spaces well, etc. 13.0 was good for most applications (I had a CHT computer case with heat sinks (lots of thin gaps) that turned out beautiful) and this next release (14.0) sorts out most (maybe all) of the remaining issues.

Try it out on your own case and let us know what you think the advantages or disadvantages are.

I am also interested to hear what others think...

can we make a cutcell cartesian mesh in icem cfd...?
 
in ansys meshing (workbench) i tried to make a cutcell mesh but i had problem in making inflation...?

cut cell method is good when your geometry cleaned properly usually used this mesh when I want to know the quick results. If I am able to understand flow physics inside flow domain its really good and helps lot. I do the rough clean up and click on cut cell run simulation..
