Hello.

I'm getting an output in one of my self-made tools:

Selecting incompressible transport model Newtonian
Selecting incompressible transport model Newtonian

I think its because if using

const dimensionedScalar& rho1 = twoPhaseProperties.rho1();
const dimensionedScalar& rho2 = twoPhaseProperties.rho2();


Can anybody tell from in which file this ouput is generated?
I want to suppress it by uncommenting the corrosponding Info code.

Thanks so far!

I think the file is generated by twoPhaseMixture.H and twoPhaseMixture.C
Am I wrong?

the output is created by the newViscosityModel.C file

transportModels/incompressible/viscosityModels/viscosityModel/newViscosityModel.C on line 48

Do you know what this interFoam line means: ?

twoPhaseProperties.correct();

Dear Isabel,

twoPhaseProperties.correct() calls a funktion you can find in twoPhaseMixture.H

twoPhaseProperties.correct() calculates the laminar viscosity by calling calcNu(), which is defined in twoPhaseMixture.C.

calcNu() calculates the kinematic viscosity nu_ which is defined as the volume averaged dynamic viscosity mu_ divided by the volume averaged density.

mu_ is also calculated in twoPhaseMixture.C as mu_ = gamma * rho1_ *nuModel1_->nu() + (scalar(1)- gamma)*rho2_nuModel2_->nu()
mu_ is the volume averaged dynamic viscosity

I hope this helps you.


Regards

Kathrin

What is the difference between twoPhaseProperties.correct() and twoPhaseProperties->correct() ? When should we use Ptr -> ?

In addition, what is turbulence->correct() ?

Default Newer Version for the .correct() function.

Hi guys,

just to comment here. I see this as an old post and I had some trouble linking it with the new versions. The functions look alike but the directories seems to have changed.

The correct function is called from the incompressibleTwoPhaseMixture.H file under the code:
virtual void correct(){calcNu();}


What is really doing? it is finding the kinetic viscosity by dividing the laminar viscosity by the average density:

// Average kinematic viscosity calculated from dynamic viscositynu_ = mu()/(limitedAlpha1*rho1_ + (scalar(1) - limitedAlpha1)*rho2_);

for further reference please lookup in the github page specified here:
