Omega.correctBoundaryConditions() changes the internal field values?

ripperjack · January 25, 2017, 12:05

Hi guys,

I am developing my own solver based on simpleFoam with the kOmegaSST model and wall functions. I notice that if I call omega.correctBoundaryConditions(), the omega internal field value (cells right next to the walls) will be changed. This is not the case for nut or k.

From my understanding, if wall function is used, the correctBoundaryConditions call will only update the wall face value. The cell values in the internal field shouldn't be changed. This behavior for omega is rather confusing... Any ideas? Thanks very much in advance!

Best regards,
Ping

BTW: I am using version 2.3.0
