Following the model manual I managed to to a one-way nested simulation using ndown. Both ndown and wrf executables ran succesfully for one additional domain, using boundary conditions from the previous model run.
I was wondering if I could use the same procedure for two additional domains. I tried to do that, but although ndown.exe ran without any problem, it produced the wrfinput file for just one domain. I there something that I have to keep in mind, or ndown can only be used for one additional domain?
Thanks in advance,
