New URL for NEMO forge!   http://forge.nemo-ocean.eu

Since March 2022 along with NEMO 4.2 release, the code development moved to a self-hosted GitLab.
This present forge is now archived and remained online for history.
step_c1d.F90 in trunk/NEMOGCM/NEMO/OPA_SRC/C1D – NEMO

source: trunk/NEMOGCM/NEMO/OPA_SRC/C1D/step_c1d.F90 @ 6140

Last change on this file since 6140 was 6140, checked in by timgraham, 9 years ago

Merge of branches/2015/dev_merge_2015 back into trunk. Merge excludes NEMOGCM/TOOLS/OBSTOOLS/ for now due to issues with the change of file type. Will sort these manually with further commits.

Branch merged as follows:
In the working copy of branch ran:
svn merge ​svn+ssh://forge.ipsl.jussieu.fr/ipsl/forge/projets/nemo/svn/trunk@HEAD
Small conflicts due to bug fixes applied to trunk since the dev_merge_2015 was copied. Bug fixes were applied to the branch as well so these were easy to resolve.
Branch committed at this stage

In working copy run:
svn switch ​svn+ssh://forge.ipsl.jussieu.fr/ipsl/forge/projets/nemo/svn/trunk
to switch working copy

Run:
svn merge --reintegrate ​svn+ssh://forge.ipsl.jussieu.fr/ipsl/forge/projets/nemo/svn/branches/2015/dev_merge_2015
to merge the branch into the trunk and then commit - no conflicts at this stage.
