CHECKIN calculates the global minimum, the maximum and the sum of the source field values (not weighted by the grid cell area) and prints them to the OASIS3-MCT debug file (for the master process of the source component model only under the attribute ``diags''). This operation does not transform the field. CHECKIN operation can significantly slow down the simulation. It should not be used in production mode.
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 $NBFIELDS
where $XMULT is the multiplicative coefficient of the source
field, which must be given as a REAL value (e.g 2.0 and not 2). $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 :
CONSTANT $AVALUE
