Hi, Im trying to execupte the WRF model for a 3 domain , this 2 nests, 1 in 1 in 1, one way nesting:
Though I successfully execute the ungrib and geogrid steps, I get the following errors in metgrid - file name: namelist.wps

[wrf_try]$ ./metgrid.exe
Processing domain 1 of 2
Processing 2016-02-09_00

But if I use the namelist.wps - (2d) (attached), the execution is successful.

Please Help

First thing I noticed is in the 3 domain case (2 nests) the max dom is set to 2 instead of 3 so it will never write the 3rd domain.

What's your data source?
 
Hello William.

My data source in ERA5. pressure and single levels. (I have used all pressure levels available (all pressure levels were used))
And Regarding domain, sorry for that error: I over looked it while trying out for 2 domain, but for 3 domain, the above error persists.

Rest of the things are same. Thank you

I don't see anything in the namelist.wps that screams error causing. Can you upload your metgrid.log files?
 
@srikar_iist
When you obtain the ERA5 data, are you getting the full global dataset, or a subset of data? This error often occurs when you're just grabbing a subset. Due to differences in map projections, the data you have sometimes lacks locations at the edges/corners of the WRF domain's boundary. To get around this, we recommend always just getting the full global dataset, or at the very least, you may have to download a bigger subset.

I am using a subset of ERA5 data. But I have made sure that The edges are well taken care off. Because Even If I try to run a 2 domain, it doesn't show any errors, with the largest - parent- domain encasing the smaller ones

Can you first run metgrid for 2 domains, and save the metgrid.log file from that run as something that indicates it is for the 2 domain run. Assuming that runs correctly, then please run it again for 3 domains. Then please attach both metgrid.log files, as well as your namelist.wps file.

Is the only change you're making to the namelist, just changing max_dom = 2 to max_dom = 3? If so, please attach the latest version of your namelist.wps file. If there are other differences in the 2 domain, vs. 3 domain simulation, please attach both namelists. Thanks!
