WRF idealized TC set up

Hi all

I am new to the idealized WRF and planning to run a sets of idealized TC simulations. The domain is 3000km by 3000km with 15km horizontal resolution (default setting so far). I used one core for a seven-day simulation (also default), which took 20 hours... I increased the number of cores, but the simulation actually slowed down. If there is anyway to improve the efficiency?

Thank you so much for your time!

Look under "WRF MODEL/Runtime Problems" for post:
"Poor performance wrf.exe with 56 core vs 16 or 28 core"

I answered the same kind of question there, I don't know if what I said works with simulation runs or not,
but it is worth trying it out.
