How to create a new module and compiled in CAM.

[nuvolet]

Greetings,

I would need to create a new independent module in the components/cam/src/physics/cam which will be need to run and used in here.
Besides the module, I also create a modified namelist_definition.xml, which includes the new variables that will called.

How can I make that this new module be compiled together with the rest of the modules in CAM?

Thanks in advance

I found a similar post but for CLM:

How to compile a new module.F90 file putted in src/biogeophys/ at my local CTSM

Hi, everyone. I recently have got an idea that need to add a new module.F90 which written by myself to change the soil freezing and thawing process. But after I put the new .F90 file in src.clm/biogeophys/, Am I should seek the .F90 file contain the main program and change the calling...

bb.cgd.ucar.edu

Should be the new module in the same path where the CMakelists.txt file is located (components/cam/src/physics/cam)?.

Thanks in advance

Hi Toni,

Apologies for the delay - the build system should find any new file you put in src/physics/cam. Once it's in there, you'll want to add the relevant use statements and call(s) to src/physics/cam/physpkg.F90

Does that answer your question?

Are those new statements in the src/physics/cam/physpkg.F90 really necessary to make run the new module?

Thanks

It's not critical that the statements are in physpkg.F90, if that's what you mean - that's just the main driver for physics so would be a likely candidate!

Wherever you want to call the new module from is fine, as long as you include the relevant use statement(s).

Plugging a new module in will be easier once we get the new CAM-SIMA model up and running, but for now you still have to add the relevant calls where necessary and make sure the variables you need are available.

Hope that helps
