Reply To: Correct CFX Pre Setup to avoid isolated fluid regions

[Mark Owens]

Hi, in my picture above there is an internal volume in brown and an external volume in green. The geometry doesn't care what the regions will later be assigtned to. At the geometry stage all you are trying to do is fill a domain with tessellating solids and assigning names to them and some of their faces. I can't see how that would result in an isolated fluid error in CFX unless you have failed to produce a connected mesh. There is a limit to how much help we can provide through the forum. Are you able to raise a support request?
