Some physics/dynamics options (and WRF-Chem) DO NOT support hybrid (DM+SM) run. If it is stuck at the beginning. try the following:
Use
#SBATCH --cpus-per-task=1andexport OMP_NUM_THREADS=1,Increase the total number of tasks, for example,
#SBATCH --ntasks-per-node=128Specify the number of tasks for each executable explicitly; for instance, use
srun -n16 ./real.exesrun -n128 -c1 ./wrf.exeor justsrun ./wrf.exe
