Hello Foamers!

I am currently trying to implement a method for calculating viscosities and thermal conductivities based on the Chapman-Enskog assumption (~Kinetic Theory method in Fluent). Starting from sutherlandTransport, this is very simple but I still have 2 questions:


1) Is it necessary to rebuild psiThermo, psiReactionThermo and psiChemistryModel equivalent classes that can handle this method of calculating transport properties or can I just make this method selectable somewhere? Since obviously at the moment the kinetic theory transport + janaf thermo is not considered a valid combination.

2) In case there's no way to make 1) work, I already went ahead and tried to build "pyThermo", ... as exact copies of the psi-equivalents, while making the necessary changes in thermoPhysicsTypes.H, PyThermos.C, pyReactionThermos.C, ... This new thermo lib compiles without a problem, as well as the pyChemistryModel lib but now comes the strange part: when I try to recompile my custom solver to use this pyChemistryModel instead of psyChemistryModel (everything exact copy, only adjusted so it can use kineticTheoryTransport), I get an undefined reference error:

Make/linux64GccDPOpt/QSSAFoam.o: In function `main':
QSSAFoam.C:(.text.startup+0x31c): undefined reference to `Foam::pyChemistryModel::New(Foam::fvMesh const&)'
collect2: ld returned 1 exit status

My solver Make/options file looks like this, so I assume the libraries are correctly linked?

Huge thank you in advance for any help you may be able to offer
