Hello,
I would like to update the alpha1 in interdyfoam at the inlet meanwhile the mesh move. I am begining with something simple like this; word inlet = "xmin"; //if (nameI == inlet) Info <<"/////////////////////// ESTOY EN EL PARCHE ///////////////////////////////// " << nl; label patchJ; patchJ=label(mesh.boundaryMesh().findPatchID(inlet )); if (mesh.Cf().component(2).boundaryMesh()[patchJ] < 0) alpha1=1; But it is giving me an error like; error: ‘class Foam::tmp<Foam::GeometricField<double, Foam::fvsPatchField, Foam::surfaceMesh> >’ has no member named ‘boundaryMesh’ advanced thanks |

I made this solution, i guess that it is possible to do it easier, any idea?
word inlet = "xmin"; //if (nameI == inlet) Info <<"/////////////////////// ESTOY EN EL PARCHE ///////////////////////////////// " << nl; label patchJ; patchJ=label(mesh.boundaryMesh().findPatchID(inlet )); const polyPatch& cPatch = mesh.boundaryMesh()[patchJ]; //if (mesh.Cf().component(2).boundaryMesh()[patchJ] < 0) alpha1=1; vectorField NN = mesh.boundary()[patchJ].Cf(); scalarField inletZ(NN.component(vector::Z)); const pointField& p = mesh.points(); forAll(cPatch, faceI) { const labelList& f = cPatch[faceI]; label nPoints = f.size(); //Info << "nada " << p[f[0]] << endl; scalarList coordZ(4); coordZ[0] = p[f[0]].component(2); coordZ[1] = p[f[1]].component(2); coordZ[2] = p[f[2]].component(2); coordZ[3] = p[f[3]].component(2); scalar maxz = coordZ[0]; scalar minz = maxz; for (int i=1; i<4; i++){ if (coordZ[i] >= maxz) maxz = coordZ[i]; if (coordZ[i] <= minz) minz = coordZ[i]; } scalar projecZ = maxz-minz; scalar newalpha=0; scalar Zpos(inletZ[faceI]); if (Zpos + 0.5 * projecZ < 0.0) newalpha = 1.0; else if (Zpos - 0.5 * projecZ > 0.0) newalpha = 0.0; else newalpha = 0.5 - Zpos / projecZ; alpha1.boundaryField()[patchJ][faceI] = newalpha; } Thanks |
