One way to do this to force how ANSYS divides up the mesh -- instead of
meshing by a certain size for all axis, you could tell it to mesh say by 10
divisions (nodes) along x, 5 divisions along y, and 4 divisions along z --
or something like that.   I don't remember exactly -- haven't done this for
a while but there is a command that break up a line into nodes.  You
partitioned the lines then mesh.
