Any idea of ,how to create a subdomain of half the size of the whole rectangular domain. I want to do this to inflate the interface of the domain to get finer mesh at the solid-gas interface. thanks in advance.

Hi MAB,

Before explaining how to do this, I suggest you simply apply an appropriate mesh control and inflate the mesh from the desired surface in the Meshing application. You should have inflation there anyhow, as this is a wall boundary.

In DesignModeler: If you want to get a volume next to your surface, you can try creating a Named Selection on the surface of interest and extruding or revolving this surface to slice out the volume you need. Alternatively, you may be able to create a thin body around the surface. It's really too difficult to describe the process in detail here, so I suggest trying a few things in DM and reviewing the on-line documentation.

HI MAB,

This can be done by making two separate geometries and combined them into CFX Pre. In Pre you can define the interface between them.
