Last change on this file since 5006 was 3535, checked in by yann meurdesoif, 6 years ago

For unstructured grid (dynamico).
A file can be used to impose land fraction without using Relief.nc.
The land franction is available at 0.05°, 0.25° and 0.5° degree resolution.
If land_water_0.05.nc or land_water_0.25.nc or land_water_0.50.nc is present in the runing directory, it will be use to impose ter/oce fraction.
