Well the good news is that my code is correct. The bad news is that I failed to
look at the exponent values of my w component values. When I looked more
closely,  I found the w values were 2-3 orders of magnitude less than the u,v
components so were essentially zero. This brings up another question. Is there
a way to set the "z" axis scaling so that it is scaled to the range of the w
component values?

Thanks again,

JO
