Error while reading physics namelist when enabling config_urban_physics

Hello,

I am trying to run MPAS-Atmosphere with urban physics enabled.
In my namelist.atmosphere file, under the &physics block, I added:

Code:
&physics
   config_sst_update        = false
   config_sstdiurn_update   = false
   config_deepsoiltemp_update = false
   config_radtlw_interval   = '00:30:00'
   config_radtsw_interval   = '00:30:00'
   config_bucket_update     = 'none'
   config_physics_suite     = 'mesoscale_reference'
   config_urban_physics     = true
/

However, when I try to run the model, I get the following error in the log:

Code:
----------------------------------------------------------------------
Beginning MPAS-atmosphere Output Log File for task       0 of      52

The run stops immediately after this message.

  • MPAS version: 8.2.0
  • Number of tasks: 52
  • I was able to run successfully without the config_urban_physics line.
  • I have tried with both "true" and ".true."

MPAS doesn't support urban physics at present. We are planning to include this capability in the near future.

Please turn off urban schemes, then try again.
