error running postwrf (on Mac laptop)

[fipoucat]

I am doing a shaded plot from wrf output but after ncl is processing, it stops with an error message:
./modules/contourlvl.sh line 149 216700 killed

Please send your namelist.wrf, as well as all messages displayed on the screen.

I suspect a memory issue, but below the screen output:

./postwrf.sh

Can you send the WRF file you tried to plot? I think your output may have some issue, or it may be related to hardware/memory.
If the WRF file size is too big, you can send output.txt below:
ncdump -h wrfout_d02_2022-06-02_15\:00\:00 > output.txt

I too think it is related to memory. I sent the problem I had on my Mac with PostWRF not working, I then installed a virtual Linux and installed PostWRF which is working.
After the error with d02 (too large and outnc.txt attached), I can run the same namelist.wrf with domains 1 and 3 and it is working.
The Mac laptop is a powerful machine but the virtual Linux is using limited memory.

So you're using a Mac laptop. There was another issue mentioning this problem. I must directly try PostWRF on a Mac laptop to figure it out.

Edit: You can also try a WRF file with a size less that 2GB to see if the same problem happens. There are some limitations for the size of NetCDF data on some machines/configurations.
