(u) Getting patchwise values
PHOENICS users working in a GROUND subroutine may require to obtain
the values of the COefficient, VALue, or net source associated with
a PATCH of which they know the name, and for a variable which they
designate. If so, they can make use of the subroutines GETCOV and
The first is activated by the statement:
which will set COEF and VALU equal to the required quantities, which
may then be printed or used in whatever ways the user requires.
The second is activated by the statement:
which sets the variable SOR as follows:
where 'avecoeff' is the average value of the COefficient over the
PATCH, 'avephi' is the average value of the variable in question
over the PATCH, and 'area etc.' equals the relevant area where
TYPE equals NORTH, SOUTH, etc; it equals the volume when TYPE equals
VOLUME; and it equals unity when TYPE equals CELL, etc.
