i tried to declare an array of type volScalarfield as-
volScalarField Xsi ( IOobject ( "Xsi", runTime.timeName(), mesh, IOobject::NO_READ, IOobject::AUTO_WRITE ), mesh, dimensionedScalar("Xsi", dimless, 0) ); volScalarField ( IOobject ( "Xsi[" + std::to_string(4) + "]", runTime.timeName(), mesh, IOobject::NO_READ, IOobject::NO_WRITE ), mesh, Xsi[4] ); which compiled well but when I added eqn in my main code as- fo<< "\nCalculating Xsi\n" << endl; for(int i =0 ; i<5 ; i++) { volScalarField& Xsii = Xsi[i]; while (pimple.correctNonOrthogonal()) { fvScalarMatrix XsiiEqn ( fvm::ddt(Xsii)-pow(1-Xsii,n)*A_1*exp(-Ea_1/(R*T)) == fvOptions(Xsii) ); fvOptions.constrain(XsiiEqn); XsiiEqn.solve(); fvOptions.correct(Xsii); }} it displayed compilation error as follows- error: invalid initialization of reference of type ‘Foam::volScalarField& {aka Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh>&}’ from expression of type ‘double’ { volScalarField& Xsii = Xsi[i]; ^ /home/anshul/OpenFOAM/OpenFOAM-dev/wmake/rules/General/transform:25: recipe for target '/home/anshul/OpenFOAM/OpenFOAM-dev/platforms/linux64Gcc62DPInt32Opt/applications/solvers/basic/ablationFoam/ablationFoam.o' failed I don't know if there is problem in my declaration of array or initialization of field Xsii Pls anyone Guide me through this. Any sort of help is highly appreciated Thank You |

if you read the error:
error: invalid initialization of reference of type ‘Foam::volScalarField& {aka Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh>&}’ from expression of type ‘double’ { volScalarField& Xsii = Xsi[i]; ^ you see that you create a reference of type volScalarField and try to reference an object of type double, which is illegal. your reference type must be the same as your referenced type. |
