Last change on this file since 5177 was 2429, checked in by Laurent Fairhead, 9 years ago

Correction on the calculation of the surface of the grid at the poles (problem was introduced
in r2222).
Due to the different distribution of OMP tasks in the dynamics and the physics, had to
introduce 2 new logical variables, is_pole_north_phy and is_pole_south_phy, and so decided
to rename the old is_north_pole/is_south_pole to is_north_pole_dyn/is_south_pole_dyn to
stay coherent and, hopefully, clear things up a bit.
