I wish to do a nested domain simulation so I've written the namelist accordingly. Now I want to see how the domain looks like. for this I am using plotgrids.ncl. But it is persistently giving me errors, I tried tweaking some parameters, using old settings (I am using WRF-4.1.1). currently, i am getting this error (I've attatched a screenshot). Also when I add type = "x11" it doesnt work, so I have to save the image as png and then open. I am atttatching namelist and plotgrid scripts as well for your referance.
