Problem: buoyancy source term for KE-EP model
 
I faced with problem concerned with inserting the volumetric production rate of KE by gravitational forces interacting with density/temperature gradients.

It is a source term in KE-EP or KE-L turbulence models.

As advised I activated the buoyancy source term by means of introducing the following PATCH and COVAL statements in the Q1 file:

PATCH (KEBUOY,PHASEM,1,NX,1,NY,1,NZ,1,1) COVAL (KEBUOY,KE,GRND4,GRND4)

After making the eardat file I found the following statements in q1ear file:

PATCH (SKIP,PHASEM,1,NX,1,NY,1,NZ,1,1) COVAL (SKIP,KE,GRND4,GRND4)

Who knows why the buoyancy source term is not activated? And what should I do to account for this source term? PHOENICS version is 3.5.0.
