Preparing an IPSLCM6 model without PISCES and ORCHIDEE for compiling and simulation

For the sake of simplicity the Schwarz algorithm was only implemented and tested without PISCES for the ocean and without ORCHIDEE for the atmosphere.

As well, regarding resolution the method was implemented on the ORCA2 grid for NEMO and a 96x95 grid for LMDZ.

The ice model retained was LIM3 which allows for greater control and is conservative.

The various steps to get a working IPSLCM6 model with these settings is now described.

IPSLCM6 model

Get the latest IPSLCM6 model from the forge repository.

In the workdir of your project, create a directory for your new IPSLCM6 installation, move into it and get modipsl by executing :

svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl

setting an ORCA2LIM3PISCES configuration in NEMOGCM/CONFIG

Since ORCA2LIM3PISCES is not a standard configuration of NEMO in the IPSLCM6 model it is necessary to create this configuration. In order to retain the latest changes to NEMO-LIM3 we use the ORCA1LIM3PISCES configuration as a template.

To do this, go into
