Summary0000871: Restart with engineTime...
DescriptionWhen restarting engine cases, the file "uniform/time" usually contains info on the time step size. This was saved in the unit seconds, but when using the engineTime-class this is interpreted as deltaCrankAngle - which normally differs orders of magnitude.
Steps To ReproduceRestart an engine case with "adjustTimeStep yes" in controlDict.
Additional InformationPresent in all OF versions AFAIK

So... adding this simple hack to the constructor (just before calling timeAdjustment()) in engineTime.C solves the issue:




    const IOdictionary controlDict
    (
        IOobject
        (
            name,
            system(),
            *this,
            IOobject::MUST_READ_IF_MODIFIED,
            IOobject::NO_WRITE,
            false
        )
    );

    IOdictionary timeDict
    (
        IOobject
        (
            "time",
            timeName(),
            "uniform",
            *this,
            IOobject::READ_IF_PRESENT,
            IOobject::NO_WRITE,
            false
        )
    );
    
    if (controlDict.lookupOrDefault<Switch>("adjustTimeStep", false))
    {
        if (timeDict.readIfPresent("deltaT", deltaT_))
        {
            deltaT_ = timeToDeg(deltaT_);
        }
    }

Changed TimeIO to write entries in <time>/uniform:time in userTime units.
