Namelist.input error with WRF 4.6.0 but not with 4.3.3 and real.exe crashes

[alainF]

Hello, I have installed WRF v4.6.0 to upgrade my previous version wich was 4.3.3. I have been using v4.3.3 for 2 years with the namelist attached to this post. Now, I have a problem with real.exe. It crashes soon after the start by issuing the following error message:

wrf@wrf-virtual-machine:~/WRF/run$ tail rsl.error.0000
taskid: 0 hostname: wrf-virtual-machine
module_io_quilt_old.F 2931 T
------ ERROR while reading namelist physics ------
Maybe here?: grav_settling = 0, 0, 0,
Maybe here?: bl_mynn_tkebudget = 0, 0, 0,

FATAL CALLED FROM FILE: <stdin> LINE: 11680
ERRORS while reading one or more namelists from namelist.input.
-------------------------------------------
application called MPI_Abort(MPI_COMM_WORLD, 1) - process 0

Was there any changes in v4.6.0 compared to 4.3.3 ?

I have erased grav_settling and bl_mynn_tkebudget from the namelist and then I get another crash from real.exe and it says :

wrf@wrf-virtual-machine:~/WRF/run$ tail rsl.error.0000

I am quite confused,

Thank you for your help

Hi,
The issue is this namelist option:

bl_mynn_tkebudget          = 0, 0, 0,

This option was removed prior to the WRFV4.6.0 release. Since you have that set to 0, it shouldn't be an issue for you to just remove it. In the future if you get errors like this, you can look in the Registry/Registry.EM_COMMON file to see that the parameters still exist.
