NewFoamer is on a distinguished road
When running simulations, it gives me the relative residual for the different matrices.

How do I obtain the relative error? Or the condition number of the matrices? Looking through the documentation, I have not been able to find a function for fvMatrix which helps me to obtain either of these?
