| Foam::functionObjects::stopAtTimeStep | |
| Description | |
| Stops the run if the time-step drops below the specified value in seconds | |
| and optionally write results before stopping. | |
| The following actions are supported: | |
| - noWriteNow | |
| - writeNow (default) | |
| - nextWrite | |
| Examples of function object specification: | |
| \verbatim | |
| stop | |
| { | |
| type stopAtTimeStep; | |
| libs ("libutilityFunctionObjects.so"); | |
| minDeltaT 1e-8; | |
| action writeNow; | |
| } | |
| \endverbatim | |
| will write the fields and stop if the time-step drops below 1e-8s. | |
| Usage | |
