equisize-skew->-0.97

Meshing success? but EquiSIZE SKEW >0.97 (11 or 16 cells)?

May have to re-fine meshing of the geometry...by:
*. coarse mesh then if need more fine mesh have to try methods below...

Because Meshing in GAMBIT automatically generated mesh (especially in 3-D) in most cases, can not provide uniformly high quality in un-structured mesh (hexahedral or tetrahedral) for complex geometry.

On the surface, the unstructured mesh does have advantages to cover large areas of complex geometry, but, in reality, a high quality mesh is always hard to obtain.

One says that need to go back to the blocking of the geometry (meshing process): to divide the geometry into smaller pieces and re-create the surface geometry so that can avoid the highly skewed cells.

**. have to try long iteration until 10^-6 criterion meet.... (already done, but still not convergence)....

have to try one by one....

And .... just an information from CFD source: it must take more time in Meshing Process and Convergence Process......
