Description
Hi,
With s-coordinates on multiple processors (4x4) ORCA2_LIM2 was failing with undefined e3
===>>> : E R R O R
===========
zgr_sco : e3w or e3t =< 0 at point (i,j,k)= 1 39
..etc
Gurvan suggested the following fix, which cured the problem. However might there be a better way of solving the problem involving adding a 4th argument to the preceding call to lbc_lnk
CALL lbc_lnk( zenv, 'T', 1._wp ) ?
$ svn diff NEMOGCM/NEMO/OPA_SRC/DOM/domzgr.F90

Implemented the quick fix solution suggested here at revision 3563. Longer term, a more generic solution to the unset ghost rows may be preferable.
