BC LIMITER - Set DQ LIMITER on coupled boundaries

Structured Grids


This keyword controls whether the DQ LIMITER is applied to coupled boundaries in structured zones. The limiter is used to improve stability by restricting the change in the solution over a single iteration. See the DQ LIMITER keyword for additional details, including how to activate the limiter within the zone volume. The default setting for the boundary limiter is OFF. The PRINT option specifies whether limiter messages should be written to the .lis list output file. When the limiter is activated, the default PRINT setting is ON. Some users find the print messages too verbose and prefer to disable them.

To ensure consistent treatment on both sides of a coupled boundary, the BC LIMITER settings apply to all structured zones rather than specified zones.
