Hi Jean-Michel,

thanks for noticing, the reason is the same as before: BU(34,18,2,1) is zero exactly. This should not happen (ever) (see seaice_lsr.F l1259, for seaicemaskU = 0., there should be ONE=1D0 remaining). The quick fix is to reset any BU and BV that are 0 to 1. but then the program stops (within gdb, testreport passes) in seaice_solve4temp because tsurfloc(3,1) = 0 for bi=bj=1, very strange.

Should I apply the quick fix for now?

Martin
