I'm attempting to add a thermophysical model (myGasThermoPhysics) to the chemistry model runtime selection table so I can use my own Cp and viscosity in my reacting simulations. I've managed to get it added to the selection table as evidenced by:

ode                psi              hollis      myJanaf      perfectGas                specie  sensibleEnthalpy

When I error out the thermoType. However, when I attempt to run the simulations I get the following error:

Selecting combustion model PaSR<psiChemistryCombustion>
Selecting chemistry type 
{
    chemistrySolver ode;
    chemistryThermo psi;
}

Selecting thermodynamics package 
{
    type            hePsiThermo;
    mixture         massAveragedMixture;
    transport       hollis;
    thermo          myJanaf;
    energy          sensibleEnthalpy;
    equationOfState perfectGas;
    specie          specie;
}

terminate called after throwing an instance of 'std::bad_cast'
  what():  std::bad_cast
Aborted (core dumped)

which basically means I've missed something. The steps I've taken to get this far are the following:

In my custom library where the custom Cp, viscosity and mixtures are defined I created 3 files with the following code sections:

#include "makeChemistrySolverTypes.H"
#include "speciesPhysicsTypes.H"
//#include "thermoPhysicsTypes.H"
#include "psiChemistryModel.H"
#include "rhoChemistryModel.H"

// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

namespace Foam
{
    // Chemistry solvers based on sensibleEnthalpy
    makeChemistrySolverTypes(psiChemistryModel, myGasThermoPhysics);

}

#ifndef reactionTypes_H
#define reactionTypes_H

//#include "thermoPhysicsTypes.H"
#include "Reaction.H"
#include "speciesPhysicsTypes.H"

// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

namespace Foam
{

    typedef Reaction<myGasThermoPhysics> myGasReaction;

}

// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

#endif

#include "makeChemistryModel.H"
#include "speciesPhysicsTypes.H"
#include "psiChemistryModel.H"
#include "chemistryModel.H"
//#include "thermoPhysicsTypes.H"

// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

namespace Foam
{
    // Chemistry moldels based on sensibleEnthalpy
    makeChemistryModel
    (
        chemistryModel,
        psiChemistryModel,
        myGasThermoPhysics
    );

}

where speciesPhysicsTypes.H defines myGasThermoPhysics

I then of course added them as make targets in the Make/files file and added the proper lnInclude folders in the Make/options file.

As far as I can tell from the source this is all I need to do to add a thermophysical model to the runtime selection for the chemistry, but I seem to be missing something given the error. Can anyone shed some light on this?
