Cubit 15.7 User Documentation
CUBIT can export models to the Fluent mesh format and supports defining the above 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) is not defined within CUBIT and must be assigned using a CFD model editor, such as Fluent.
The following shows the commands for creating and modifying CFD boundary conditions. To delete them, use the delete command (see Miscellaneous Commands).
