boundaryFoam, axisymmetry and turbulence models
1 Attachment(s)
Hello,
I am trying to obtain a fully developed velocity profile in a duct at low Reynolds number (Re ~ 6000) by using an axisymmetric geometry with boundaryFoam. I would like to use the k-omega SST turbulence model, but I get a strange error that seems to occur at initialization of the turbulence model object:
Code:

I also get this error for other low-Re turbulence models (LamBremhorstKE, LienCubicKELowRe, LienLeschzinerLowRe), while the case runs when "RASModel" is set to "laminar". However, boundaryFoam works with the komegaSST model for a channel geometry as in the tutorial.
Am I doing something wrong? Is it even possible at all to use boundaryFoam in an axisymmetric setting? The files are attached.
Thanks in advance!
