Hello everybody,

I am simulating a simple pipe flow with a heated pin in it with forced and natural convection. When I run the Solver with the full buoyancy model (variable density) everything is fine. But when I try to use the boussinesq model (constant density, but a value for the thermal expansivity) i get this error:

Error detected by routine PEEKR
CDANAM = ../../HEATM/TFC/SIGMA/VALUE
CRESLT = NONE

Current Directory : /FLOW/PHYSICS/ZN1/FL1/TURBM/BUOYTURB

I think maybe a value 'Sigma' is missing, but I dont know how I can fix it. Did anyone have a similar Problem or any idea how to fix it?

Thank you, CFDJ
