You could make its expression in cfd post or the best way is to export the y plus variable to cfd post from Fluent

hello, if i am using k-epsilon a and i over-refine my mesh, will the solver take longer or will it know automatically to clip the y+ to 11, hence for k-epsilon is it worth just being over refined (since there would be no expense of computational time)?

I am struggling with this one, how can I find y+values because I don't know, what values can I take for kinematic viscosity and dynamic viscosity. Even k-omega how much y+values needed. Tell me plz
