Dear OpenFOAM uses and Developers

I request the forum users to shed some light on the details of how MULES works. Please share the information if anybody is aware of it.

I looked into the code and this is what it contains:

1) overloaded function templates for
--> explicitSolve - bounds can be supplied as the function argument;

--> explicitSolve01 - for a scalar bounded between 0 and 1;

--> implicitSolve01 - for a scalar bounded between 0 and 1;

and a function template for

--> limiter

InterFoam uses the MULES solver to solve for the volScalarField gamma and calls

MULES::explicitSolve01(gamma, phi, phiGamma).

This eventually calls the function template

template<class>
void Foam::MULES::explicitSolve
(
volScalarField& psi,
const surfaceScalarField& phi,
surfaceScalarField& phiPsi,
const SpType& Sp,
const SuType& Su,
const scalar psiMax,
const scalar psiMin
)


with Sp = zero
Su = zero
psiMax = 1.0
psiMin = 0.0

Could anybody please comment what does template arguments: class SpType, class SuType stand for?

Thanks in advance

I think they are representing eventual source terms in the advection equation. There is even this possibility :
with field rho.

How can I call this special MULES function (I need to provide both source terms and rho) ?

I do :

But it doesn't compile... What's wrong ?:confused:

Cheers,

Did you look at interPhaseChangeFoam?

See: http://foam.sourceforge.net/docs/cpp/a02688_source.html

yeah, I got it. it was because I should have written geometricOnesField() in place of OneField().

Thanks !

Hi Jaswinder, how you doing? MULES is an Flux Corrected Transport explicit solver for hyperbolic equations. Its implementation mostly follow the ideas of Zalesak limiter but the 's are calculated iteratively. I'm going to give some details in my thesis soon but that's the basic idea.

Regards.

Hey Jaswi,

I am new entry in this OpenFOAM interFoam solver learners list. Can you share some notes and ideas with me regarding VOF treatment, flow through porous media and other programming aspects in OpenFOAM.

Hi Jaswinder,


I have just started learning the interFoam Solver in OpenFoam V9. I would be very grateful if you could send me some notes. my email id is;
