◆ initializeFrom()

void oofem::StructuralPenaltyContactBoundaryCondition::initializeFrom ( InputRecord & ir )

overridevirtual

Initializes receiver according to object description stored in input record. This function is called immediately after creating object using constructor.

Note that initializeFrom may be called mutiple times.
