[MITgcm-support] Interpolation issue: wet grid-pts with theta=0 identically

[Juncheng Zhang]

Dear all,

I am using MITgcm to run a 1km high-resolution simulation based on the tutorial reentrant channel,
I first run a 5 km simulation, then use the output of 5km run as the initial condition of my 1km run,
However, after I  did the interpolation of 5 km output, and run the model, the error said below:

(PID.TID 0000.0001) *** ERROR ***  INI_THETA: found      2891 wet grid-pts with theta=0 identically.
(PID.TID 0000.0001) *** ERROR ***  If this is intentional, you need to set checkIniTemp=.FALSE. in "data", namelist PARM05

I know wet grid-pts relates to the parameter hFac? But I don’t know how to fix it,

And I tried to ignore this error by adding checkIniTemp=.FALSE., however, the simulation is not stable, and I had weird numerical artifacts appearing.

Thank you in advance, I appreciate any help.
