Orifice plate
 

Can anyone suggest how I can mesh an orifice plate in a pipe where the mesh is finer at some regions. In an esdu report it gave list for expansion factors. How do I input these values? below is the mesh i am trying to create.

Thank you.

software? if its icem, block it and set edge values (spacing and ratio)

I am trying meshing and running it in workbench fluent.

divide geometry into five regions
1. regions on left and right of orifice
2. regions below regions just created and orifice.

for above region create edges and then faces and mesh them. I am assuming you are using gambit

Still having problems meshing this. I have a technical report that gives wall element height and different expansion factors for the regions. However I don't know what they mean and how to apply it in gambit. Anyone know? Thank you.
