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

axisymmetric solve, negative volume, sphere
