seapy.couplings.couplingpointstructural.CouplingPointStructural

class seapy.couplings.couplingpointstructural.CouplingPointStructural(name, system, **properties)

Bases: seapy.couplings.coupling.Coupling

Model of a point coupling between structural components.

__init__(name, system, **properties)

Constructor.

Parameters:

• name (string) – Identifier
• junction (seapy.junctions.junction) – junction
• subsystem_from (seapy.subsystems.Subsystem) – subsystem from
• subsystem_to (seapy.subsystems.Subsystem) – subsystem_to
