hi friends
i am doing a project on stirred tank for my post graduation theses but i am totally new to Ansys. i have made my geometry in design modeler and created interface between rotating region(impeller) and stationary region(fluid) but when i run it in fluent using MRF it shows
"Note: zone-surface: cannot create surface from sliding interface zone.
Creating empty surface."
i am not sure whether my geometry is incorrect or i am applying wrong boundary conditions
plz help

It sounds like you have both MRF and sliding mesh enabled somehow. Check your boundary and cell zone conditions to ensure they are all MRF and not sliding mesh.
