Default behaviour assumes operating in incompressible mode. To apply to compressible RAS cases, use the -compressible option. \*---------------------------------------------------------------------------*/ #include "fvCFD.H" #include "incompressible/singlePhaseTransportModel/singlePhaseTransportModel.H" #include "incompressible/RAS/RASModel/RASModel.H" #include "nutkWallFunction/nutkWallFunctionFvPatchScalarField.H" #include "basicPsiThermo.H" #include "compressible/RAS/RASModel/RASModel.H" #include "mutkWallFunction/mutkWallFunctionFvPatchScalarField.H" #include "wallDist.H" // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // void calcIncompressibleYPlus ( const fvMesh& mesh, const Time& runTime, const volVectorField& U, volScalarField& yPlus ) { typedef incompressible::RASModels::nutkWallFunctionFvPatchScalarField wallFunctionPatchField; #include "createPhi.H" singlePhaseTransportModel laminarTransport(U, phi); autoPtr RASModel ( incompressible::RASModel::New(U, phi, laminarTransport) ); const volScalarField::GeometricBoundaryField nutPatches = RASModel->nut()().boundaryField(); bool foundNutPatch = false; forAll(nutPatches, patchi) { if (isA(nutPatches[patchi])) { foundNutPatch = true; const wallFunctionPatchField& nutPw = dynamic_cast (nutPatches[patchi]); yPlus.boundaryField()[patchi] = nutPw.yPlus(); const scalarField& Yp = yPlus.boundaryField()[patchi]; Info<< "Patch " << patchi << " named " << nutPw.patch().name() << " y+ : min: " << min(Yp) << " max: " << max(Yp) << " average: " << average(Yp) << nl << endl; } } if (!foundNutPatch) { Info<< " no " << wallFunctionPatchField::typeName << " patches" << endl; } } void calcCompressibleYPlus ( const fvMesh& mesh, const Time& runTime, const volVectorField& U, volScalarField& yPlus ) { typedef compressible::RASModels::mutkWallFunctionFvPatchScalarField wallFunctionPatchField; IOobject rhoHeader ( "rho", runTime.timeName(), mesh, IOobject::MUST_READ, IOobject::NO_WRITE ); if (!rhoHeader.headerOk()) { Info<< " no rho field" << endl; return; } Info << "Reading field rho\n" << endl; volScalarField rho(rhoHeader, mesh); #include "compressibleCreatePhi.H" autoPtr pThermo ( basicPsiThermo::New(mesh) ); basicPsiThermo& thermo = pThermo(); autoPtr RASModel ( compressible::RASModel::New ( rho, U, phi, thermo ) ); const volScalarField::GeometricBoundaryField mutPatches = RASModel->mut()().boundaryField(); bool foundMutPatch = false; forAll(mutPatches, patchi) { if (isA(mutPatches[patchi])) { foundMutPatch = true; const wallFunctionPatchField& mutPw = dynamic_cast (mutPatches[patchi]); yPlus.boundaryField()[patchi] = mutPw.yPlus(); const scalarField& Yp = yPlus.boundaryField()[patchi]; Info<< "Patch " << patchi << " named " << mutPw.patch().name() << " y+ : min: " << min(Yp) << " max: " << max(Yp) << " average: " << average(Yp) << nl << endl; } } if (!foundMutPatch) { Info<< " no " << wallFunctionPatchField::typeName << " patches" << endl; } } int main(int argc, char *argv[]) { timeSelector::addOptions(); #include "addRegionOption.H" argList::validOptions.insert("compressible",""); #include "setRootCase.H" #include "createTime.H" instantList timeDirs = timeSelector::select0(runTime, args); #include "createNamedMesh.H" bool compressible = args.optionFound("compressible"); forAll(timeDirs, timeI) { runTime.setTime(timeDirs[timeI], timeI); Info<< "Time = " << runTime.timeName() << endl; fvMesh::readUpdateState state = mesh.readUpdate(); // Wall distance if (timeI == 0 || state != fvMesh::UNCHANGED) { Info<< "Calculating wall distance\n" << endl; wallDist y(mesh, true); Info<< "Writing wall distance to field " << y.name() << nl << endl; y.write(); } volScalarField yPlus ( IOobject ( "yPlus", runTime.timeName(), mesh, IOobject::NO_READ, IOobject::NO_WRITE ), mesh, dimensionedScalar("yPlus", dimless, 0.0) ); IOobject UHeader ( "U", runTime.timeName(), mesh, IOobject::MUST_READ, IOobject::NO_WRITE ); if (UHeader.headerOk()) { Info << "Reading field U\n" << endl; volVectorField U(UHeader, mesh); if (compressible) { calcCompressibleYPlus(mesh, runTime, U, yPlus); } else { calcIncompressibleYPlus(mesh, runTime, U, yPlus); } } else { Info<< " no U field" << endl; } Info<< "Writing yPlus to field " << yPlus.name() << nl << endl; yPlus.write(); } Info<< "End\n" << endl; return 0; } // ************************************************************************* //
