The current RANS turbulence model requires a Reciprocal Wall Distance variable.
Make sure that all the study steps solving for the flow variables in this physics interface get their initial values of variables not solved for from a study step that has already computed the corresponding Reciprocal Wall Distance variable.

thanks in advance
If you encounter the mentioned error in COMSOL Multiphysics with a RANS turbulence model, ensure proper initialization of the Reciprocal Wall Distance variable in study steps. Confirm correct settings for turbulence model and wall treatment, validate boundary conditions, and check solver settings. Consult COMSOL documentation for model-specific guidance. If issues persist, contact COMSOL support for assistance. Review and ensure proper definition and initialization of all required variables in accordance with RANS turbulence model requirements.
