Detailed Description

This function object overrides the calculation time step.

Can only be used with solvers with adjustTimeStep control (e.g. pimpleFoam). It makes no attempt to co-operate with other time step 'controllers', e.g. maxCo, other functionObjects. Supports 'enabled' flag but none of the other options 'timeStart', 'timeEnd', 'writeControl' etc.

Usage

Example of function object specification to manipulate the time step:

setTimeStep1
{
    type        setTimeStep;
    libs        (utilityFunctionObjects);

    deltaT      table ((0 5e-4)(0.01 1e-3));

    ...
}

Where the entries comprise:

Property	Description	Required	Default value
`type`	Type name: setTimeStep	yes
`enabled`	On/off switch	no	yes
`deltaT`	Time step value	yes
`timeStart`	Start time	no	0
`timeEnd`	End time	no	GREAT
`deltaTCoeff`	Time step change limit	no	GREAT
