yPlusRAS
|
|
|
|
Description
|
|
Calculates and reports yPlus for all wall patches, for the specified times
|
|
when using RAS turbulence models.
|
|
|
|
Default behaviour assumes operating in incompressible mode. To apply to
|
|
compressible RAS cases, use the -compressible option.
|
|
|
|
Extended version for being able to handle two phase flows using the
|
|
-twoPhase option.
