Cubit 16.18 User Documentation
CUBIT can export models to the Fluent mesh format and CNGS unstructured mesh format for CFD analysis. CUBIT also supports defining the below CFD boundary conditions. Only the region on which the BC acts can be defined in CUBIT. The data associated with each boundary condition (pressure, velocity, mass values, etc.) is not defined within CUBIT and must be assigned using a CFD model editor, such as Fluent.
