| Class | |
| Foam::functionObjects::setTimeStepFunctionObject | |
| Description | |
| Updates the time step as a Function1 of time. | |
| If the case is running with userTime specified in controlDict then the | |
| time-step values returned by the Function1 are assumed to be in user-time | |
| rather than real-time. | |
| Makes no attempt to cooperate with other timeStep controllers (i.e., solver | |
| courant number control or other functionObjects). In general any value set | |
| here will be overwritten by solver time-step adjustment if enabled, so for | |
| this to work 'adjustTime' should be switched off. This is compatible with | |
| 'adjustableWriteTime', in which case the time-step values set will not be | |
| exactly as specified, but write intervals will be matched exactly. | |
| This function supports the 'enabled' flag but none of the other run | |
| controls; 'startTime', 'endTime', 'writeControl', etc... | |
