Hi All,
is it possible to calculate condition number of the class fvMatrix? Well, I'm looking for some criteria, which would describe the conditionality of the equation system. Thanks. Michal |

Computing the condition number of a matrix requires computing eigenvalues. Computing eigenvalues of a big sparse matrix resulting from discretization of a mesh is somewhat also hard than solving Navier Stokes system.
Maybe you should say why you need such a computation. Are you really really sure it is necessary? |
