Hi Dear Foamers.

I'm working with openFoam 2.0.1,and have a problem with solver (interPhaseChangeFoam) in multiphase solvers.

I want to add (surface tension or sigma ) in a part of this solver, in directory:
/run/myinterPhaseChangeFoam/phaseChangeTwoPhaseMixtures/SchnerrSauer/SchnerrSauer.c
I added sigma() in this code:

Foam::tmp<Foam::volScalarField>
Foam:haseChangeTwoPhaseMixtures::SchnerrSauer: Coeff
(
const volScalarField& p
) const
{
volScalarField limitedAlpha1(min(max(alpha1_, scalar(0)), scalar(1)));
volScalarField rho
(
limitedAlpha1*rho1() + (scalar(1) - limitedAlpha1)*rho2()
);
return
//......I want to change it( <<sigma>> surface tension multiple in it):
(3*rho1()*rho2())*sqrt(2/(3*rho1()))*sigma()
*rRb(limitedAlpha1)/(rho*sqrt(mag(p - pSat()) + 0.01*pSat()));
//.................................................. ......
}

dont successful wmake, and seen(was not declared ):

phaseChangeTwoPhaseMixtures/SchnerrSauer/SchnerrSauer.C:113: error: sigma() was not declared in this scope
make: *** [Make/linux64GccDPOpt/SchnerrSauer.o] Error 1

please help me

Hi again Dear foamers.

I added interpolate(interface.sigma())
in this code:

Foam::tmp<Foam::volScalarField>
Foam:haseChangeTwoPhaseMixtures::SchnerrSauer: Coeff
(
const volScalarField& p
) const
{
volScalarField limitedAlpha1(min(max(alpha1_, scalar(0)), scalar(1)));
volScalarField rho
(
limitedAlpha1*rho1() + (scalar(1) - limitedAlpha1)*rho2()
);
return
//......I want to change it( <<sigma>> surface tension multiple in it):
(3*rho1()*rho2())*sqrt(2/(3*rho1()))*interpolate(interface.sigma())
*rRb(limitedAlpha1)/(rho*sqrt(mag(p - pSat()) + 0.01*pSat()));
//.................................................. ......
}

dont successful wmake, and seen(was not declared ):
