I used two types of meshing: tetrahedrons and cutcell. I run both under the exact same conditions.
The only difference is the type of mesh (tetraheral vs. cutcell) and the # of elements for each type of mesh and the quality (inherent problems of the type of mesh used).
My solution always diverges when I use the cutcell mesh. I always receive the "temperature is limited to...." during iterations. When I do a case check with the cutcell mesh, i receive the warning that the cell skewness is over the recommended 0.98. I do not receive this warning when I use the tetrahedral mesh.

Is cell skewness really that important? Important enough to cause divergence, particularly in the energy residual?
