[MITgcm-support] Warning and time stepping issue

[Anthony Coletti]

Hi all,

I am trying to run a course 32x32x15 (6 faces) run to get some preliminary data.  Unfortunately, my time step will not exceed 5000.s.  ~ Two minutes into the run, it crashes and I get the corresponding error::

WARNING: r*FacC > hFacSup at       1 pts : bi,bj,Thid,Iter=   4   1   1       106
 e.g. at i,j=   2   1 ; rStarFac,H,eta =  2.028435  2.200000E+01  2.262556E+01
WARNING: r*FacC > hFacSup at       1 pts : bi,bj,Thid,Iter=   4   1   1       107

WARNING: r*FacW < hFacInf at       2 pts : bi,bj,Thid,Iter=   2   1   1       108

If you need any other info, please let me know.  Any help would be appreciated!


Thanks!
