FLUENT Problem

I did a mesh check in FLUENT and received the error "symmetry zone 54 has two adjacent cell zones." What does two adjacent cell zones mean? I tried searching for this error to no luck.

I think you have fluid zone (or domains) at both the sides of symmetry, making symmetry as an internal face, or interface between two domains, which is not allowed. Try correcting your model by deleting the fluid zone at one side of symmetry or specify the symmetry such that it doesn't have any zone at the other side.

Why do you need the fluid domain at both the sides of symmetry? symmetry is used so that you don't have to use a full geometry but only half one, because the flow structure in the other half is exactly mirror image of the one you are simulating! Remove the domain at one side of the symmetry, otherwise you won't be able to simulate.

If we're thinking of the same thing, then I may have already removed it in design modeler with the symmetry feature. I attached an image of what I mean. Red is my symmetry surface. Not sure if this matters, but i tried simulating yesterday without solving that error and the solutions started diverging at about 30 iterations. Would this kind of error affect convergence? Thanks!
