Summary0002290: tmp deallocation in twoPhaseEulerFoam and reactingTwoPhaseEulerFoam with implicitPhasePressure
DescriptionIn twoPhaseEulerFoam if implicitPhasePressure is on and nAlphaCorr > 1, the solver crashes because alpha1alpha2f gets deallocated during the first iteration of solving alpha. Similar thing happens in reactingTwoPhaseEulerFoam, but instead of crashing, the implicit solution step is omitted in the later iterations because alphaDbyA is no longer valid.

Is there a reason that nAlphaCorr shouldn't be > 1 with implicitPhasePressure or that the implicit step should be solved only once? If not, both problems can be fixed by using () after the terms in laplacian so that they don't get cleared.

Thanks for the report and suggested fix. While the combination of implicitPhasePressure with nAlphaCorr > 1 is unlikely to be very useful there is no reason why it should not be possible.
