Class
Foam::fvCellZone
Description
cellZone selection or generation class with caching of zone volume
for fvModels, fvConstraints, functionObjects etc.
The cellZone is either looked-up from the mesh or generated by a
zoneGenerator and stored locally.
Usage
Examples:
\verbatim
// Select all cells
cellZone all;
// Select the cells within the given cellZone
cellZone rotor;
// Select the cells within the given box
cellZone
{
type box;
box (3.48 -0.1 -0.1) (3.5 0.1 0.1);
}
// Select the cell containing the given point
// and update the cells with respect to the fixed points
// if the mesh moves
cellZone
{
type containsPoints;
moveUpdate true;
points ((0.075 0.2 0.05));
}
\endverbatim
