negative volume with sphere
i want to model a natural convection over a sphere using fluent. u can see part of my mesh.
the problem is that when the fluent is in 2d solve mode the grid check is ok and i have no problem but when fluent is in axisymmetric, the grid check sends negative volume error, i dont know waht is the problem i uses many kindes of mesh types even tri elememts but i cant solve the problem.

in 2D axis symmetric, the axis has to be identical with the x-coordinate (so flow from left to right or from right to left).
All points have to be on positive y.

remesh the boundary of the sphere with more nods
