How can two tangent interfaces gliding along each other be defined in CFX-10.0 Pre?



Edit CCL and add in the respective boundary section for the interface side the following syntax:

BOUNDARY: int1 Side 1
Boundary Type = INTERFACE
Location = INT1 1
BOUNDARY CONDITIONS:
MASS AND MOMENTUM:
Option = Conservative Interface Flux
END

###############################
MESH MOTION:
Displacement X Component = hub(t)
Displacement Y Component = 0 [m]
Displacement Z Component = 0 [m]
Option = Specified Displacement
END
###############################

TURBULENCE:
Option = Conservative Interface Flux
END
END
END

The Options for Mesh Motion are the same as available for other types of boundaries in CFX-10.0 Pre.
