◆ forceEquationNumbering()

int oofem::StokesFlow::forceEquationNumbering ( int i )

overridevirtual

Forces equation renumbering on given domain. All equation numbers in all dofManagers are invalidated, and new equation numbers are generated starting from domainNeqs entry corresponding to given domain. It will update numberOfEquations variable accordingly. Should be used at startup to force equation numbering and therefore sets numberOfEquations. Must be used if model supports changes of static system to assign new valid equation numbers to dofManagers.
