Hello everyone!
From what I've gathered, multiphaseEulerFoam is a LES-based solver. Since I intend to include population balance equations to this solver, I would like to use a less computationally intensive turbulence modelling (RAS). I'm trying to modify the solver so that the turbulence model may be switched from the case directory using turbulenceProperties. I made the following changes:
1. In the file multiphaseEulerFoam.C
Code:
#include "LESModel.H"
to
Code:
#include "turbulenceModel.H"
and,
Code:
sgsModel->correct();
to
Code:
turbulence->correct();
2. In the file createFields.H

Code:
autoPtr<incompressible::LESModel> sgsModel
    (
        incompressible::LESModel::New(U, phi, fluid)
    );
to
Code:
autoPtr<incompressible::turbulenceModel> turbulence
    (
        incompressible::turbulenceModel::New(U, phi, fluid)
    );
3. In the file UEqns.H

Code:
volScalarField nuEff(sgsModel->nut() + iter().nu());
to
Code:
volScalarField nuEff(turbulence->nut() + iter().nu());
4. In the file Make/options added the following lines:
Code:
-I$(LIB_SRC)/turbulenceModels/incompressible/turbulenceModel \
Code:
-lincompressibleTurbulenceModel \
Is this all that should be changed in the solver? The solver compiles fine after making these changes in OF 2.3.x. In OF 2.1.1, however, I get a lot of errors.
