In single phase unsteady simulations that use sliding, moving, or dynamic meshes, an alternative Rhie-Chow flux treatment can be enabled that includes an additional transient term in the formulation. This is expected to yield improved results in these cases. To enable the alternative Rhie-Chow formulation, enable beta features and use the following TUI command:

Alternative Rhie-Chow flux treatment for unsteady sliding, moving, and/or dynamic mesh? [no] yes
