Turn off Surface Sensible Heating (HFX) from the WRF Simulation

[Shak]

Dear WRF Community,

I am trying to run a case by turning off Surface Sensible Heating (HFX) from the simulation. I use the Revised MM5 for the surface layer physics (option 1 in namelist.input). I got some ideas from this previous thread.
I modify module_sf_sfclay.F file
I changed the line:
HFX(I)=FLHC(I)*(THGB(I)-THX(I))
to
HFX=0
I am not sure if I need to modify the line: HFX(I)=AMAX1(HFX(I),-250.)
I re-compiled it and ran the simulation.
But the modeling results didn't change at all after this.

Is my modification correct? Did I do anything wrong?

It would be highly appreciated If someone could help me.
Thanks in advance.

Warmly
Shak

Shak,
I believe your approach is correct. However, you need to modify the code module_sf_sfclayrev.F.
Please try again and let me know how it works.
Remember to recompile WRF after code modification.
