petrile_83 is on a distinguished road
I'm beginner using open foam and I try to model very simple heat transfer problem. Elbow with 2 inlets and one outlet
HTML Code:
Model works fine without heat tranfer. But when I solve with buoyantBoussinesqSimpleFoam I get following error message:

create time

Create mesh for time = 0

Reading g
Reading thermophysical properties

Reading field T

Reading field p_rgh

Reading field U

Reading/calculating face flux field phi

Selecting incompressible transport model Newtonian
Creating turbulence model

Selecting RAS turbulence model kEpsilon

--> FOAM FATAL ERROR: Invalid wall function specification
Patch type for patch inlet1 must be wall
Current patch type is patch

What patch type I should use for inlets and outlet? Seems bit strange to use wall for inlet. Is buoyantBoussinesqSimpleFoam solver right choice for this application?
