OpenFOAM solver applications typically include core functionality such as turbulence modelling, heat transfer, and buoyancy effects.
Further flexibility is offered via
fvOptions—a collection of run-time
selectable finite volume options to manipulate systems of equations by adding
sources/sinks, imposing constraints and applying corrections.
Selecting the region🔗
The majority of options are applied to collections of mesh cells. These can
be selected according to the entry
selectionMode entries include:
all: all cells
cellZone: cells defined by a cell zone. This requires an additional entry to specify the name of the cell zone, e.g.
selectionMode cellZone; cellZone myCellZone;
myCellZone is the name of the cell zone
cellSet: cells defined by a cell set. This requires an additional entry to specify the name of the cell set, e.g.
selectionMode cellSet; cellSet myCellSet;
myCellSet is the name of the cell set.
points: a list of points. This requires an additional entry to list the points, e.g.
selectionMode points; points ((0 0 0) (1 1 1) (2 2 2));
