CHECKIN calculates the global minimum, maximum, mean, and sum of the source field values taking the mask into consideration. If a grid area or fraction field is also available, (respectively in the file areas.nc or masks.nc), then the area and/or fraction weighted mean and sum are also diagnosed and written. Information about masking and weighting is written to the output file. All diagnotics are written to the master process OASIS3-MCT debug file (under the attribute “CHECK* diags”). This operation does not transform the field. CHECKIN operations can slow down the simulation and should not be used in production mode. For backward compatibility, CHECKIN has one generic input line that is no longer used but is still required and can contain anything. See also CHECKOUT.
The generic input line is as follows:
# CHECKIN operation INT = 1
BLASOLD allows the source field to be scaled and allows a scalar to be added to the field. The prior ability to perform a linear combination of the current coupling field with other coupling fields has been deprecated in OASIS3-MCT. This transformation occurs before the interpolation per se.
This transformation requires at least one configuring line with two parameters:
# BLASOLD operation $XMULT $NBFIELDSwhere $XMULT is the multiplicative coefficient of the source field. $NBFIELDS must be 0 if no scalar needs to be added or 1 if a scalar needs to be added. In this last case, an additional input line is required where $AVALUE is the scalar to be added to the field, which must also be given as a REAL value :
