Hello, I am trying to simmulate a simple measuring section with rectangular profile and a bluff body in it.The geometry is symmetrical, so I decided to model only half of the geometry in 2D.I defined the cutting mirror-edge as symmetry (boundary condition). When reading the grid in Fluent the following warning appears: Warning: It appears that symmetry zone 3 should actually be an axis(it has faces with zero area projections). Unless you change the zone type from symmetry to axis, you may not be able to continue the solution without encountering floating point errors. I would be very thankful, if someone has a suggesting how to solve the problem. Kind Regards Gerd

I'm having the same problem. I'm modelling a simple case of bubble rise in a liquid and fluent shows the same error. I have changed the BC to axis but it didn't work.

Let me know if you got any solution to this.
