Regional Configuration

Hi all, I have been trying to set up a regional configuration of CICE (standalone).   I have generated a dipole grid  requried for the region as follows with 1degree resolution.dimensions:
    y = 76 ;
    x = 36 ;variables:
    int cellId(y, x) ;
    double elevation(y, x) ;
    int kmt(y, x) ;
    double ulat(y, x) ;
    double ulon(y, x) ;
    double htn(y, x) ;
    double hte(y, x) ;
    double hus(y, x) ;
    double huw(y, x) ;
    double angle(y, x) ;A closed boundary condition is used in the north and the south and  open boundaries in the east and west. Also ice restoration and temperature resoration is given in the model.  But the model fails to iterate and gives the following error  picard convergence failed!

 ice_therm_mushy solver failure

Any  suggestion  is much appreciated. If anyone can provide a useful resoursce to regional modeling using CICE would be of great help. ThanksSiva
