Hello,

I have a problem with my OF 2.3.x application in interFoam. I have altered that solver such that in case of a wrong calculation (e.g. divergence), the calculation is cancelled and I return back in back in time to restart using some other settings (e.g. smaller time step). This works ok so far. First, I store my time position:

        time_start = runTime.timeOutputValue();
        time_start_i = runTime.timeIndex();

The fields (U, p, alpha1 etc.) have to be stored too. If the calculation goes bust, I can retrieve the time and return back where I have been when things were still ok:

                // return back to previous time step

                runTime.setTime
                ( 
                    time_start,
                    time_start_i
                );

                // decrease time step a little

                runTime.setDeltaT (8e-1*runTime.deltaTValue(),false);
                deltaTadj = runTime.deltaTValue();

The code works so far, but, for reasons I do not understand the value writeInterval in controlDict gets altered (around tripples, but maybe a coincidence). Can somebody help me to correct this?

Regards,

Daniel
