properties of solid mixture
 
Hi every one,

i use chtMultiRegionFoam solver which contains in its 0 folder these parameters Ypmma, and Ychar, which i suppose after searching to be component of mixture for solid region.

in the tutorial case this solid model is used:

thermoType constSolidThermo;

in log file chtMultiRegionFoam.log properties are listed for solid region like this:
Code:

*** Reading solid mesh thermophysical properties for region innerTube

    Adding to thermos

Constructed constSolidThermo with
    rho        : rho [1 -3 0 0 0 0 0] 8000
    Cp        : Cp [0 2 -2 -1 0 0 0] 450
    K          : K [1 1 -3 -1 0 0 0] 80
    Hf        : Hf [0 2 -2 0 0 0 0] 0
    emissivity : emissivity [0 0 0 0 0 0 0] 0
    kappa      : kappa [0 -1 0 0 0 0 0] 0
    sigmaS    : sigmaS [0 -1 0 0 0 0 0] 0

in order to test solid mixture i changed the solid model by this one:

thermoType solidMixtureThermo<multiComponentSolidMixture<cons tSolidTransport<constSolidRad<constSolidThermo<con stRho>>>>>;

and changed some values of Ypmma, and Ychar. when looking in log file to see calculated properties i didn't found values instead i found this:
Code:

*** Reading solid mesh thermophysical properties for region innerTube

    Adding to thermos

can any one tell me how to find values of the properties to insure how solver calculated solid mixture properties ?

thanks in advance :)
