| Foam::zeroFieldField | |
| Description | |
| A class representing the concept of a field of zeroFields used to | |
| avoid unnecessary manipulations for objects which are known to be zero at | |
| compile-time. | |
| Used for example as the density argument to a function written for | |
| compressible to be used for incompressible flow. | |
