Hi every one.
I want to model elbow erosion with fluent. The reference paper generate a mesh like the uploaded picture. How can I create mesh like it?
Tahnks alot.

Hi Hadkam90,

This is the o-grid kind of mesh you would like to generate.

You can do this in ANSYS meshing by following the steps below

1. Add a Multizone method to your pipe.

2. Add a Face meshing control to the cylindrical face of interest. Ensure that Mapped mesh is switched to "On"

3. Right click on the Multizone method and select "Inflate this method". Then specify the desired number of inflation layers you would like to have.

4. Generate mesh.

Or you can slice your geometry into a square and the four 45 degree angles, then "create part" in ansys design modeler.
Then use line sizing mesh commands and mapped face meshing. to achieve your desired mesh.

if you are using ansys meshing and cfd
