giveNewEq()

int oofem::Natural2GlobalOrdering::giveNewEq ( int leq )

overridevirtual

Finds the global equation from a local equation.

Parameters

leq	Local equation number.

Returns

Global equation number.

Returns

the total number of equations of the problem.

giveNumberOfLocalEqs()

int oofem::Natural2GlobalOrdering::giveNumberOfLocalEqs ( )

inlineoverridevirtual

Returns number of local eqs; ie. those that belong to receiver processor; Note that some eqs may be owned by remote processors (some shared nodes,...). The sum of local eqs for all processors should give total number of eqs.

Returns
