Which source code of clm5 describes the update of leaf carbon

[Xueli Huo]

Hi

When I run an ensemble CLM experiment, some of the ensemble members generate NaN leafc. Someone knows how the leaf carbon are updated in clm5.0 ?
I will be so appreciated if explicit source code/file are pointed out.

Thanks

Leaf carbon (leafc) is updated in several routines, from the fluxes:
biogeochem/CNCStateUpdate1Mod.F90
biogeochem/CNCStateUpdate2Mod.F90
biogeochem/CNCStateUpdate3Mod.F90

In general, look for places where leafc_patch(p) appears on the left hand side of an equation.
