Hi All, Can anyone please
Can anyone please inform me as to how I can get the magnitude of a vector defined as volVectorField, which I belive is of type GeometricField. I have tried mag() an a lot of other manipulations. In essence I need to get the magnitude of the velocity U (defined as volVectorField) and multiply it with other values defined as dimensionedScalar. I am getting a compile error.
Please please help.
Thanks in advance,
Hi Susan, something like
dimensionedScalar C ("C",p.dimensions(),1000.0) ;
volScalarField magU = C*mag(U);
U is again the velocity defined as volVectorField
hope it helps
Thanks for the response, my pr
Thanks for the response, my problem is like this
scalar x, y, z
z = x*y*mag(U) where U is volVectorField
gives me an error
no match for 'operator=' in 'Re = Foam::operator/(const Foam::tmp<foam::geometricfield<type,> >&, const Foam::dimensioned<double>&) [with Type = double, PatchField = Foam::fvPatchField, GeoMesh = Foam::volMesh](((const Foam::dimensioned<double>&)((const Foam::dimensioned<double>*)(& nu))))'

If with scalar you mean just d
If with scalar you mean just dimensionedScalar the problem is:
z must be a volScalarField
Hi Susan, you get the error b
you get the error because you try to assign to a scalar variable the product between a scalarField and a volScalarField.
You can get it working if you write:
volScalarField z = x*y*mag(U)
I hope it has been useful,
Thanks so much! It takes a whi
Thanks so much! It takes a while to understand how the different classes are structured.
