Sponge Layer visc_factor

[hpftcb]

Hello,

I'm trying to set a sponge layer in roms3.6 as described in this post https://www.myroms.org/projects/src/ticket/627. I have set

LuvSponge == T ! horizontal momentum
LtracerSponge == T T T ! temperature, salinity, inert

The problem is Roms isn't reading visc_factor and diff_factor from my grid file. Is there any flag I have to set to force Roms to read these variables?

Thanks in advance

Do you have ANA_SPONGE turned on? You can look at get_grid.F to see that that's the flag controlling the reading of those fields along with LuvSponge and LtracerSponge.
