      Use the following TUI command to speed up the transient run. solve/set/rotating-mesh-flow-predictor? yes Using above TUI command, Transient simulations that involve a rotating fluid zone utilize a better flow field predictor that can speed up the calculation. You can deactivate the flow predicting by answering “No”. Though user can use large time steps, it is always recommended that mesh should not move more than cell length in one time step.
