Class
    Foam::functionObjects::adjustTimeStepToNucleation

Description
    Controls the time-step to the minimum nucleation time scale. A specific
    nucleation model can be specified, otherwise it will scan for and use all
    the nucleation fvModels in operation.

    Note that this function only does anything if time step adjustment is
    enabled in the controlDict.

    Example of function object specification:
    \verbatim
    adjustTimeStepToNucleation
    {
        type            adjustTimeStepToNucleation;
        libs            ("libmultiphaseEulerFunctionObjects.so");
        maxCo           0.1;
    }
    \endverbatim

Usage
    \table
        Property     | Description             | Required    | Default value
        type         | type name: adjustTimeStepToNucleation | yes |
        model        | name of the nucleation fvModel | no   |
        maxCo        | maximum nucleation "Courant" number | no | 1
    \endtable
