quad4 : volume loads in the x direction were incorrect and did not account for shell thickness.
tria3 : volume loads did not account for shell thickness.
fe_mknl : assembly did not work for mixed of_mk and .m files elements.
fe_mk assembly does not work negative volumes. You must
use model.Elt=feutil('orient',model) to reorient volumes prior
to assembly. The patched version returns an error rather than a warning when
this problem occurs.
spfmex : complex matrix solvers led to a memory deallocation problem. This bug is currently fixed on Windows and HP-UX.
