Introduction to CFX -Interfaces, Sources and Additional Variables

Domain Interfaces are used for:
Connection of mismatched meshes (hex to tet for example)
The meshes may be in the same or different domains
“Domain” in Domain Interfaces is a little misleading
A single mesh file may contain non-matching mesh regions and require domain interfaces
Changes in reference frames between domains
Even if the mesh matches
Connect different types of domains together (e.g. Fluid to Solid)

Create periodic regions within a domain






After creating a domain interface 3 new object are created in the outline tree

The interface object is at the Flow Analysis level
This is the object you should edit to make changes to the domain interface
Within each domain a Side 1 or Side 2 boundary condition is automatically created
In general do not edit these objects
They will be automatically updated when changes are made to the interface object
