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
