Summary0003132: Computing heat transfer with StationaryPhaseModel in reactingMultiphaseEulerFoam fails
DescriptionWhen I try to add some heat transfer to the bed tutorial case of reactingMultiphaseEulerFoam, the solver fails to run the simulation.

It seems the solver is unable to create or solve the energy equation of the StationaryPhase.

The solver crashes, when I try to use the pureStationaryIsothermalPhaseModel phase model, with or without heat transfer models.

Interestingly, the solver does not always crash, when I run it with valgrind.


Has heat transfer in conjunction with the stationary phase model been tested so far?
Steps To ReproduceGo to the "bed" tutorial of reactingMultiphaseEulerFoam

change in phaseProperties the type of the "solid" phase from "pureStationaryIsothermalPhaseModel" to "pureStationaryPhaseModel" to enable heat transfer modelling
change in fvSolution the value of nOuterCorrectors to 1; if we leave the setting at the value 3, then the solver will fail during the first time step; if we use 1, then the solver will not crash immediately.

run reactingMultiphaseEulerFoam

The solver will fail with a segmentationFault




So far, we tried to run the case without any heat-transfer models enabled.


Add heat transfer models in the file phaseProperties

heatTransfer

    (solid in air)
    {
        type RanzMarshall;
        residualAlpha 1e-3;
    }
    
    (solid in water)
    {
        type RanzMarshall;
        residualAlpha 1e-3;
    }
);


Additional InformationInterestingly, when I run

valgrind reactingMultiphaseEulerFoam

then, after some lengthy valgrind-output, the solver will run, yet compute rubbish

Here is a bit of the solvers output

new cannot satisfy memory request.
This does not necessarily mean you have run out of virtual memory.
It could be due to a stack violation caused by e.g. bad use of pointers or an out of date shared library

I think you are the first person to try this. There was a bug in that the handling of some of the tmp fields in the multiphase energy equations. Fixed in dev and 6.
