source: LMDZ6/trunk/libf/dyn3dmem/mod_const_mpi.F90 @ 4543

Last change on this file since 4543 was 4146, checked in by Laurent Fairhead, 3 years ago

Source code and xml files needed for XIOS output in the LMDZ LonLat? dynamical core.
One flag controls everything: ok_dyn_xios. Parameters controlling outputs need to be put in the xml
files, nothing is set in the code
Work to follow on the dynzon file and the modipsl/libIGCM framework.
ok_dyn_xios = n should not change anything
