HI All,
...urs kind attention is required, actully my problem is calculation at boundary. so its similar to Anja Stretz's problem .his prob. is.. Here it is: #include "fvCFD.H" #include "incompressible/singlePhaseTransportModel/singlePhaseTransportModel.H" #include "incompressible/turbulenceModel/turbulenceModel.H" int main(int argc, char *argv[]) { # include "setRootCase.H" # include "createTime.H" # include "createMesh.H" # include "createFields.H" # include "initContinuityErrs.H" Info<< "\nStarting time loop\n" << endl; // Change bc: // Get index of patch label inletPatchID = mesh.boundaryMesh().findPatchID("inlet"); // Get reference to boundary field value fvPatchVectorField& inletu = U.boundaryField()[inletPatchID]; // get coordinate for cell centres const fvPatchVectorField& centre = mesh.C().boundaryField()[inletPatchID]; scalarField x = centre.component(vector::X); scalarField y = centre.component(vector::Y); scalarField z = centre.component(vector::Z); scalar n_1 = 0.159159; scalar n_2 = -0.030791; dimensionedScalar a ( "a", dimensionSet(0, -1, -1, 0, 0, 0, 0), scalar(0.826871257), ); dimensionedScalar s ( "s", dimensionSet(0, 1, -1, 0, 0, 0, 0), scalar(4), ); vector Cp = vector::zero; dimensionedScalar d ( "d", dimensionSet(0, 1, 0, 0, 0, 0, 0), scalarField(mag(mesh.C() - Cp)), ); scalarField Ux = sqrt((s-d*d*a)*(s-d*d*a)/(n_1*n_1 + n_2*n_2))* n_1; scalarField Uy = sqrt((s-d*d*a)*(s-d*d*a)/(n_1*n_1 + n_2*n_2))* n_2; scalar Uz = 0.0; inletu = vector(Ux, Uy, Uz); U.write(); Info<< "ExecutionTime = " << runTime.elapsedCpuTime() << " s\n\n" << endl; Info<< "End\n" << endl; return(0); } .......in my case it is preesue , temperatures also ,...its error on inletu=vector(..);..i commented it. but even values are not updating of inletp for pressure ,and inlett for temperature which are scalars...someone tried such problem?..thanks |
