I have a problem when I use the high roughness (icing) model instead of standard one. I am simulating 2D flow on rough flat plate the roughness are given as an equivalent sand grain roughness profile.
the problem that I am getting this massage
wall_transition_coeffs: Unknown bc type
Internal error at line 3000 in file 'turbulencesg_ke.c' on Node 6
and the solution goes very slow. when i use the standard roughness model i have no problem or when I disable the intermittency equation.
will be great if someone helped me with this issue.

"Additional Roughness Models for Icing Simulations" of Fluent 2020 User Guide, the high roughness model is compatible only with Spalart-Allmara and SST k-w. it is not compatible with transitions models
