This is useful to write results before a case fails due to uncontrollable
automatic time-step reduction, usually caused by unstable pressure-velocity
coupling.
Class
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
\table
Property | Description | Required | Default value
type | type name: stopAtTimeStep | yes |
minDeltaT | Minimum time-step [s] | yes |
action | Action executed | no | writeNow
