Dear Colleagues,

I would like to set parent_grid_ratio as 1:7, 1:9, 1:11, 1:13, 1:15, 1:17, 1:19 and 1:21 to simulate, but the WRFDomainWizard could not generate i_parent_start, j_parent_start, e_we, e_sn automatically. Could you please give any advice? And can WRF simulate too large parent_grid_ratio?

Best wishes,
Stella
 
Stella,
As is mentioned in this best practices page, it is never advised to use a ratio any larger than 5:1. Unfortunately the WRFDomainWizard is no longer developed or supported, and when it was, it was managed by a different group (outside of NCAR).
