I have been working from sample scripts to run ndown for 2 domains, and I have a question. I know that I need to run real.exe, then wrf.exe to process a coarse grid, then modify namelist.input to run real.exe for 2 domains for the 2 domain example, then run ndown. My question is, to run for 3 domains, do I run the coarse grid, do I make a 2 domain run, then run ndown, then make a 3 domain run, and run ndown again, or do I just make a 3 domain run after the coarse grid run, and then run ndown? I hope this isn’t confusing!
