| Foam::distributions::multiFixedValue | |
| Description | |
| Distribution which comprises a list of fixed values with given | |
| probabilities. The probabilities are normalised so that they sum to one, so | |
| they can be provided as fractions or percentages or with any other | |
| arbitrary scale factor. | |
| Usage | |
| Example usage: | |
| \verbatim | |
| { | |
| type multiFixedValue; | |
| values | |
| ( | |
| (1e-6 30) | |
| (2e-6 60) | |
| (5e-6 10) | |
| ); | |
| } | |
| \endverbatim | |
