CFD Online Discussion Forums - chtMultiRegionFoam, error while when defining the thermodynamic properties

Hello,

I seem to have an error while defining my fluid thermophisycal properties.

Code:

Adding to thermoFluid



Selecting thermodynamics package hRhoThermo<pureMixture<constTransport<specieThermo<hConstThermo<perfectGas>>>>>

#0  Foam::error::printStack(Foam::Ostream&) in "/opt/openfoam210/platforms/linux64GccDPOpt/lib/libOpenFOAM.so"

#1 *Foam::sigFpe::sigHandler(int) in "/opt/openfoam210/platforms/linux64GccDPOpt/lib/libOpenFOAM.so"

#2 * in "/lib/x86_64-linux-gnu/libc.so.6"

#3 *Foam::hsRhoThermo<Foam::pureMixture<Foam::constTransport<Foam::specieThermo<Foam::hConstThermo<Foam::perfectGas> > > > >::calculate() in "/opt/openfoam210/platforms/linux64GccDPOpt/lib/libbasicThermophysicalModels.so"

My thermophysicalpropertiesfiles is defined as follow :

Code:

thermoType     hRhoThermo<pureMixture<constTransport<specieThermo<hConstThermo<perfectGas>>>>>;







mixture

{

    specie

    {

        nMoles          1;

        molWeight       28.9;

    }

    thermodynamics

    {

        Cp              1000;

        Hf              0;

    }

    transport

    {

        mu              1.8e-05;

        Pr              0.7;

    }

}

I did try to replace my fluid region by a solid one, and I could avoid this error.
So I guess that hRhoThermo... is using a constant which is null and ill defined but I can not find which one. Any idea of where I should be looking ?

I can run the tutorial with the same law (hRhoThermo<pureMixture...), so something is wrong with one of my boundary condition, or constant file.
I did copy the whole tutorial chtmultiregionsimplefoam, and then I replaced the polymesh folder, and run my own blockMesh, snappyhexmesh, toposet, and splitMeshRegion.

Thanks in advance,
Romain
