Choose Data|Data Calculator and build size grid function, call it "error". This
function should be close to zero. Areas with large values indicate node spacing
that does not match the target spacing. If the spacing is too far off, contact

is the error/size, call it "pcnt_err". Areas with red color point to the elements,
which are bigger than the target size, so refinement may be warranted.
