does somebody can explain,


how fluid fractions in multiphaseInterfoam are defined ?



i success to add heat transfer equation to interFoam , compressibleLesInterFoam and bubbleFoam solvers


for example this :

volScalarField k
(
IOobject
(
"k",
runTime.timeName(),
mesh,
IOobject::READ_IF_PRESENT
),
alpha1*k1 + alpha2*k2
);

volScalarField Cp
(
IOobject
(
"Cp",
runTime.timeName(),
mesh,
IOobject::READ_IF_PRESENT
),
alpha1*Cp1 + alpha2*Cp2
);




but not for multiphaseInterFoam. i always fail. i can not use directly fluid fraction symbol (i.e alpha1 and alpha2) in this solver.



the fraction formula which defined in the multiphaseInterFoam/multiphaseMixture is not same as other interFoam family solvers.


please i really need help

that somebody can explain clearly the multiphaseMixture in multiphaseInterFoam

Hi, Nugroho, have a good day!
How about your progress on the multiphaseInterFoam? My research will also include adding heat transfer equation to it. The research topic is shown on
http://www.cfd-online.com/Forums/ope...lculation.html
And now I try to use the RASModel rather than laminar, but I meet an error like follows. Any comments?
Thank you.
