qibintj is on a distinguished road
hello, Foamers

I am trying to modify the scalarTransportFoam solver TO solve these following equation.



# include "readSIMPLEControls.H"
volScalarField nu1=DO2*pow(DT*(1-S),Tor);
volScalarField nu2=Kp*S*S*S/Nu*(-1*Sigma)*0.5*pow((DT/Kp),0.5)*(-4.24*S+3.789*S*S);
volScalarField jc=(1-S)*Tcu*(T/CO2)*exp(-alpha*F*Eta/(R*T1));
for (int nonOrth=0; nonOrth<=nNonOrthCorr; nonOrth++)
{
solve
(
//fvm::ddt(T)
fvm::div(nu1,T)
+(1/(4*F))*jc
);
solve
(
//fvm::ddt(S)
fvm::laplacian(nu2,S)
-(1/(2*F))*jc*M
);
}

}


there is always problem.
