Hi,


I am currently trying to run a simulation where I compute transport properties and Cp with polynome so my thermotype part of thermophysicalProperties looks like:

thermoType
{
    type            hePsiThermo;
    mixture         pureMixture;
    transport       polynomial;
    thermo          hPolynomial;
    equationOfState perfectGas;
    specie          specie;
    energy          sensibleEnthalpy;
}

when I run the code, I get:

--> FOAM FATAL ERROR:
Unknown fluidThermo type
thermoType
{
    type            hePsiThermo;
    mixture         pureMixture;
    transport       polynomial;
    thermo          hPolynomial;
    equationOfState perfectGas;
    specie          specie;
    energy          sensibleEnthalpy;
}


Valid fluidThermo types are:

hePsiThermo     homogeneousMixture         const       hConst       perfectGas                specie  sensibleEnthalpy  

hePsiThermo     homogeneousMixture         sutherland  hConst       perfectGas                specie  sensibleEnthalpy 

........

So it seem that this combination is not available (why?) and so I need to add this it.

I think I have to add it in psiThermos.C, but I don't know a lot about programming OpenFOAM. I have found no tutorial explaining how to do it, but I have followed a tutorial that explain how to modify a solver (http://openfoamwiki.net/index.php/Ho...ure_to_icoFoam), but I don't know how to adapt it to modify this library (or whatever it is called).
Do you know a well explained tutorial for doing that?




Thank you for your help.

Ok I have found a way to do that, for those who are interested:

I have copied /opt/openfoam7/src/thermophysicalModels/basic/
into my user directoty

Then add the wanted combination of properties into the file psiThermos.C (it is in the subdirectory psiThermo).
Then replace "LIB = $(FOAM_LIBBIN)/libfluidThermophysicalModels" by "LIB = $(FOAM_USER_LIBBIN)/libfluidThermophysicalModels"in the "files" file of the Make subdirectory of the directoty basic
run wclean
run wmake.



As I'm not very comfortable with openfoam programming, I would like to have a document that explain how to creates/change libraries. I have read the chapter 3 of the openfoam user guide but I find that it is quite light, do you have something to recommand ?
