Dear all,

I was trying to run RegCM-4.3.5.6 with-CLM for resolution of 20km.
Pre-Processing  succeed. While I got this error when I 
start the model.

The model runs successfully and reaches the end if I set iy = 96, jx = 224 (for 50km)
 leaving other parameters  ( ds, dt, ... ) unchanged.


Could you please give me some advise ? thanks.
