Hi,all

I use OF2.3.1, coding wall condensation model of H2O gas, in rhoReactingBuoyantFoam.
In YEqn.H, I add Mass source term in YiEqnMatrix.
But compile does'nt pass.
I intend to reduce H2O Mass from near wall cell, not considering water liquid phase.

In Yeqn.H, judgeing species H2O or Others, decide mass source term field value "Mass_source" or Zero value.
but zero value does not recieved.

"Mass_source" is volScalarField.

<< Yeqn.H source Code >>
fvScalarMatrix YiEqn
(
fvm::ddt(rho, Yi)
+ mvConvection->fvmDiv(phi, Yi)
- fvm::laplacian(turbulence->muEff(), Yi)
==
reaction->R(Yi)
+ fvOptions(rho, Yi)
+ (Yi.name() == "H2O" ? Mass_source :0.0 )
);

<< Compile Error >>
YEqn.H:32:48: error: no match for ternary ‘operator?:’ (operand types are ‘bool’, ‘Foam::volScalarField {aka Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh>}’, and ‘double’)
+ (Yi.name() == "H2O" ? Mass_sou :0.0 )


So I'm programing beginner, I don't know what I shoud do.
Can anyone help me?

best regard.

(sorry for bad english ...)

Hi,


"Mass_source" is volScalarField, but 0.0 is just a double.

The operator "?" needs two values with the same type (or implicit type conversion exists).


OpenFOAM have zero class. I'm not sure it works here or not.


Defining volScalarField with zero value or using if statement before the creation of fvScalarMatrix YiEqn may work, i guess...
It may not be elegant code...

Hello,snak.

Thank you for reply.

I thought there was a simpler way, but I know there wasn't.
it was nice to know that.
So I write if statement before YiEqn, and it works.

OF is so complex...

Hi,
I am also getting the same error when using the ternary operator. Can you share us how did you implement if statement before fvSclarMatrix to achieve mass_source condition

Thanks,
