Hi Jim,

What kind of display type are you using? If it is Color-Filled Contour
[plan view] I'd suggest checking the contour interval and minimum /
maximum values in Dashboard -> Displays -> < current display > . IME
IDV tends to default to a range value that ends up cropping the
extreme values, resulting in black areas. You might have to set values
beyond the actual data range to get it to work!

Best Regards,
