[RegCNET] horizontal resolution < 2km

[Chao Tang]

Dear all,


I was trying to simulate in 500m horizontal resolution by RegCM-4.5.0.

However when I tried a horizontal resolution finer than 2 km, (ds < 2), I got this error running terrain:

===================================================
Doing Horizontal Grid with following parameters
 iy     =          140
 jx     =          180

          MINLON =    55.0000000000000
          MAXLON =    58.0000000000000

===================================================

ds=2 is all fine.

How could I simulate in 500m resolution by RegCM ?

Thanks in advance for any idea about this.
