[w d]

Dear all,
   I find a new error in in runing RegCM4 from 2009123118 to 20100101 about CFL VIOLATION.
   I know usually dt< 3ds.
   I try to some dt and ds parameters,but I failed every test from 2009123118 to 2010010100.
   these failed  tests about dt&ds:
       ds=50   dt=150
       ds=50   dt=100
       dt=60    dt=150
       dt=60    dt=120
       dt=60    dt=90
  How to solve the error about CFL VIOLATION?
 
  Anthers,I try to modify idate1,idate0and idate2,and the same error is found. 
 
 
the failed message is followed.
BCs are ready from   2009123118   to   2010010100
