Dear Colleges,

I am not able to run the WRF model with the swint_opt=2 using mp_physics =17 (NSSL), the following error message appears:

However, I was not able to find in the WRF manual any specifications regarding the usage of specific mp_physics options with the newly introduced swint_opt==2 in the WRF V4.2

Kind regards,
Artur
 
Hi,
I agree that this is confusing and there isn't any clear documentation indicating what should be used. I've reached out to some colleagues who may be able to provide some insight. I'll keep you posted.
 
Hi,
It looks like these are the microphysics options that you can use with swint_opt=2 in V4.2:
Code: 
(config_flags%mp_physics  .eq. THOMPSON .or.        &
         config_flags%mp_physics  .eq. THOMPSONAERO .or.    &
         config_flags%mp_physics  .eq. NSSL_2MOM .or.       &
         config_flags%mp_physics  .eq. NSSL_2MOMG .or.      &
         config_flags%mp_physics  .eq. NSSL_2MOMCCN .or.    &
         config_flags%mp_physics  .eq. WSM3SCHEME .or.      &
         config_flags%mp_physics  .eq. WSM5SCHEME .or.      &
         config_flags%mp_physics  .eq. WSM6SCHEME .or.      &
         config_flags%mp_physics  .eq. WSM7SCHEME .or.      &
         config_flags%mp_physics  .eq. WDM5SCHEME .or.      &
         config_flags%mp_physics  .eq. WDM6SCHEME .or.      &
         config_flags%mp_physics  .eq. WDM7SCHEME .or.      &
         config_flags%mp_physics  .eq. nuwrf4icescheme .or. &
         config_flags%mp_physics  .eq. JENSEN_ISHMAEL .or.  &
         config_flags%mp_physics  .eq. P3_1CATEGORY .or.    &
         config_flags%mp_physics  .eq. P3_1CATEGORY_NC .or. &
         config_flags%mp_physics  .eq. P3_2CATEGORY    ) ) then

There is a pull request to allow this to work with all MP physics options, but that won't be released until V4.2.1. If you are interested, you can take a look at that here: https://github.com/wrf-model/WRF/pull/1197
