Maximum cell skweness
In Tgrid, there might be a need to access maximum cell skewness( Mesh--->Tri/Tet/Controls/Refinement) through
a scheme command. A typical application of this command is in a Tgrid scheme file which is used to
refine mesh with a logical statement for cell skewness.
1)To set maximum cell skew
(isetvar 'max-cell-skew) 0.6
where 0.6 is maximum cell skew
2)To get maximum cell-skew.
