CLM3.5 output problem

hello All,

I am a new user of CLM3.5, currently, I met a problem in its DGVM mode.
The values of 'lat' in .hv file are always vacant at the two highest latitudes,
which should be 85.09653, 87.8638 (64*128 resolution) I have no idea if it is a bug or correct---- results in other latitudes seems all reasonable, and I can plot
h0 file smoothly ---- but when i plot .hv file, I got this message:

warning:IrTransSetValues: error creating spline approximation for trYCoordPoints; defaulting to linear
warning:_NhlCreateSplineCoordApprox: Attempt to create spline approximation for Y axis failed: consider adjusting trYTensionF value

I tried to set the lat from 1 to 62, which avoids the missing 63 and 64, but this message still comes out.

Is there anyone who have met this problem before? hope your reply soon! thanks!
