Running real.exe for nested domain

[aisazau]

I am new to WRF and I am trying to run the model for a nested domain (D1 and D2, I attach the namelist). I have metgrid files for all the times in Domain 1, and just for the initial time (met_em.d02.2018-11-01_00:00:00.nc) in Domain 2 (as further times should not be needed). However, when running real.exe, after it runs for D1, it processes the initial time for D2 but then stops when trying to find the second met_em.d02 file (see the rsl.out.0000 output below). The met_em.d02.2018-11-01_01:00:00.nc does not exist because I thought it was not needed. Am I wrong? Is that warning "normal"? I do not see any "real.exe run successfully" at the end because it stops running after the FATAL CALLED, however, wrfinput_d01, wrfinput_d02 and wrfbdy_d01 are generated.

Thank you for your help.

From rsl.out.0000:

Hi,
I believe the issue is that you are using sst_update=1, and when you use that option, you need to have met_em* files for all times, and not just the initial time for d02. If that's the reason you're getting the error, I will admit the error message is not clear and will make a note to have this modified in the code. As a test, you could just try to turn off sst_update and see if it gets you past that error for real.exe. Let me know!

Thank you, you were right. Turning off sst_update solved the issue. I will run Metgrid again just for D2 as it is a long simulation and I want to update SST. Thank you again!

That's great to hear! Thanks for updating.
