compute compoents of U

zikou55 · September 28, 2020, 09:18

Hello, I want to define new variable in the solver
F=U.component(1)*beta; //beta is an constant

but I got an error

error: no match for ‘operator=’ (operand types are ‘Foam::volScalarField {aka Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh>}’ and ‘Foam::tmp<Foam::GeometricField<Foam::Vector<doubl e>, Foam::fvPatchField, Foam::volMesh> >’)
F=U.component(1)*beta;

please any help or suggestion and Thank you .

first of all you need to declare your variable in the following manner:

volScalarfield F(U.component(1)*beta);
