    v27 v28  
    1515I'm getting occasional failures with a segmentation fault in icb_ground in eORCA1 and eORCA025 built from the latest dev_merge_2017 branch (after several months of integration). I think icb_ground is acting as an error trap for NaN values produced in ice_dyn_rhg_evp. I will try to trace it back further next week. (Dave Storkey).

    17 '''Update 21 Feb:''' This looks like some kind of instability which doesn't get picked up by the checks in stp_ctl. There is very thick ice (~100m) at a single point which I think results in a divide-by-zero in sbc_isf_div. It looks different to the instability in the the 300 timestep ORCA2LIM3PIS_ST run in SETTE, which doesn't show any abnormally thick ice.

There is very thick ice (~100m) and a negative top-level thickness (e3t) at a single point which I think results in a divide-by-zero in sbc_isf_div. It looks different to the instability in the the 300 timestep ORCA2LIM3PIS_ST run in SETTE, which doesn't show any abnormally thick ice.
