Check compatibility with OASIS coupler #5
Description
The OASIS coupler (see documentation, Section 2.2.3) supports 5 types of grid partitioning, including the Box partition approach we use in our domain decomposition. The definition of the boxes is similar, i.e., each partition is described by its upper left corner and its local extents in the X and Y dimensions, where X is the first dimension and Y is the second. However, in our tool the upper left corner is described by coordinates, assuming Y is the fastest increasing dimension (our tool uses C-compatible ordering internally), while in OASIS it is described by a single global offset, assuming X is the fastest increasing dimension (OASIS uses Fortran-compatible ordering internally). An example of a box partition over 3 processes for OASIS is shown below:
