Summary0002245: chtMultiRegionFoam initial deltaT independent of deltaT in controlDict when using adjustTimeStep
DescriptionWhen using adjustTimeStep in chtMultiRegionFoam, the initial time step can be very huge and the deltaT entry is not used in its calculation.
This is also in contrast to the usual behavior of OF solvers.

In setInitialMultiRegionDeltaT.H change

        min(maxCo/CoNum, maxDi/DiNum)*runTime.deltaT().value(),


        min(maxCo/CoNum, maxDi/DiNum)*runTime.deltaT().value(),
        min(runTime.deltaT().value(), maxDeltaT)

This reproduces the behavior known from setInitialDeltaT.H

Steps To ReproduceCan be reproduced with any chtMultiRegionFoam tutorial like multiRegionHeater, for example.
