| Foam::fv::fixedTemperature | |
| Description | |
| Fixed temperature equation constraint | |
| Usage | |
| \verbatim | |
| fixedTemperature | |
| { | |
| type fixedTemperature; | |
| cellZone all; | |
| phase gas; // Optional phase name | |
| // Uniform temperature constraint | |
| mode uniform; | |
| temperature constant 500; // Uniform temperature | |
| // // Looked-up field temperature constraint | |
| // T T; // Temperature field name | |
| } | |
| \endverbatim | |
| Note: | |
| The 'uniform' option allows the use of a time-varying uniform | |
| temperature by means of the Function1 type. | |
