Hi,
I think it would be very useful if we could write viscosities (visc2_p,visc2_r or visc4_p,visc4_r) and diffusivities (diff2, diff4) to the his / avg / dia files. This would greatly help debugging sponge layers coded in ana_hmixcoef.h.
Similar functionality for ana_nudgcoef.h might be useful to others too.
Thanks,
Deepak
