[IDV #COT-972342]: Loading 3D Fields in IDV

Hi Josh-

It ends up being a problem with the no units again.  U10 and V10 are aliases
for grid relative u and v winds.  So, the derived field is to create 
true winds and that code expects units convertible with m/sec which the
Vis5D units are not.  The 3D Grid derived field is for grid relative 
flow vectors not true.

You can use the Grids->Create flow vectors formula and select U10 and V10
for now.  I've changed the code to account for these Vis5D units and the
fix will be in the next successful nightly build.

Sorry, I don't.  In the file you sent, it looks like TKE_MYJ varies from
.1 to 2.1.  Is there a particular area you are trying to highlight?  Have
you tried setting the range on the color bar to accentuate the area of
interest?  For example, if you are trying to highlight the area between 1.8
and 2, then set the color range (right click on the color bar in the
legend and select Change Range...) to be 1.8 to 2.0 and select a color table
with good contrast between the ends (VisAD works pretty well).  Values less
than 1.5 will be the same color as 1.5 and values > than 2 will be the same
color as 2.
