Finds the global equation from a local equation.

Parameters

leq	Local equation number.

Returns

Global equation number.

int oofem::Natural2GlobalOrdering::giveNumberOfLocalEqs ( )

inlinevirtual

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

Numbering of local equations.

Finds the local equation number from a global equation.

Parameters

eq	Global equation number.

Returns

Local equation number.
