Defining a cell zone in ANSYS meshing for fluent
 
Hi there,

As the title says, I am trying to define a cell zone in ANSYS meshing from a subset of the mesh.

The point of this is that in fluent I have wall motion, and I need to perform remeshing. The issue I am facing is that I have areas of local refinement within the domain, and so I need to specify different size criteria otherwise; A) the course regions will re-mesh to a tighter mesh in the first time step and the mesh size will blow up, or B) the refined mesh zone will un-refine itself as the simulation progresses.

Fluent can allow you to specify different re-mesh criteria for separate cell zones, but I am having trouble defining the cell zone.

The local refinement performed in ANSYS meshing is done using a body of influence, and I feel like there should be a way to use that same body to define the cell set/zone. But I cant find it.

Can anyone shed some light on how to define a cell zone, either within ANSYS meshing or with fluent?

Cheers
Stephen

I am having a similar problem. Does anyone have an idea how to solve it?
