ERROR: full bin spectral microphysics should not be used

[MSdueon12]

I am running into a fatal error while trying to execute ./real.exe and ./wrf.exe using WRF v4.5.1 and WPS v4.5. My experiment uses three nested domains, and I am attempting to use the Full Bin Spectral Microphysics scheme (mp_physics = 32).

However, the model aborts with the following error message:

--- ERROR: full bin spectral microphysics should not be used

--- ERROR: use fast version instead (mp_physics=30)

-------------- FATAL CALLED ---------------

NOTE: 3 namelist settings are wrong. Please check and reset these options

Environment Details:

• Version: WRF v4.5.1 / WPS v4.5
• System: Derech Cluster (/glade/work/zhouxu/)

I have attached my full rsl.error and namelist.input files for reference.

Is the full bin scheme (option 32) restricted in this version, or do I need to recompile WRF with specific flags to enable it? I would appreciate any guidance on it.

Thank you in advance for your help!
Xu

Hi Xu,
The full version of the spectral microphysics was discontinued a few years ago. The developers added that error message to encourage users to opt for the fast version, instead. You can read more about it in the code commit message.
