How to look at the coefficients from fvMatrix

marco7 · September 10, 2008, 12:23

Hi All,
I'm trying to look at the coefficients from fvMatrix. Is there an easy way to print or look at them.
So far I figured out that fvMatrix is derived from lduMatrix and the adressing is in fvMesh but I found no method to ouput the coefficients.

For a GeometricField I can construct a object with an IOobject which is really nice. Can I do something similar for fvMatrix?
Thanks in advance!
Marco

From the fvMatrix.H file, it looks like the Ostream operator is overloaded to handle output:

template<class>
Ostream& operator<<(ostream&>& fvm)
{
os <<>(fvm) << nl
<< fvm.dimensions_ << nl
<< fvm.source_ << nl
<< fvm.internalCoeffs_ << nl
<< fvm.boundaryCoeffs_ << endl;

os.check("Ostream& operator<<(ostream&,>&");

return os;
}

Try using Info << yourFvMatrix << endl;
