Hi Foamers,

i'm pretty new to OpenFoam and i need to extract the Coefficient Matrix from icoFoam and write it in a file.
If i have understood how icoFoam works the Coefficient Matrix is UEqn.
So is there a command to write it in a file?

Hiiiii Andrea,
You can print coefficient matrix on the terminal while solving the U equation using Info<< UEqn.upper() <<endl; , Info<< UEqn.diag() << endl;, Info<< UEqn.lower() << endl;

You can get more information on lower and diag and upper triangular matrices in here
