symmetric vs nonsymmetric system

Hi,

FEFLOW includes solver for symmetric and nonsymmetric system. But how do you know if your system is symmetric or nonsymmetric?

Thanks,

Quinn

The latest version FEFLOW 6.2 will tell you. In general, the flow simulation in most cases leads to a symmetric equation system, the transport simulation to a nonsymmetric one. There are exceptions, though, e.g., depending on the solution scheme unsaturated flow may lead to a nonsymmetric flow equation system.
