This fvModel applies a mass source to the continuity equation and to all field equations, in a zero-dimensional case. Correction is made to account for the mass that exits the domain due to expansion in space, so that the model correctly applies a total mass flow rate. It is implemented as a light wrapper around the massSource model.

Foam::polyCellSet
|
|
|
|
Description
|
|
General run-time selected cell set selection class for polyMesh
|
|
|
|
Currently supports cell selection from:
|
|
- a set of points
|
|
- a cellSet
|
|
- a cellZone
|
|
- all of the cells.
|
|
|
|
Usage
|
|
Examples:
|
|
\verbatim
|
|
// Select all cells
|
|
select all;
|
|
|
|
// Select the cells within the given cellSet
|
|
select cellSet; // Optional
|
|
cellSet rotor;
|
|
|
|
// Select the cells within the given cellZone
|
|
select cellZone; // Optional
|
|
cellZone rotor;
|
|
|
|
// Select the cells containing a list of points
|
|
select points; // Optional
|
|
points
