class DummyNode: public DomainComponent

DomainComponent

DummyNodes are a type of node created and used by Subdomains for their exterior nodes. They reference a real node and most methods invoked on them are in turn invoked by the dummy node on the real node. The calls asking the real node to change its current state are ignored. The calls involving DOF_Group are handled by the dummy node.

To construct a dummy node which is associated with the node pointed to by theRealNode.

Each DummyNode, when involved with a StaticCondensationAnalysis analysis, will be associated with a DOF_Group object. It is the DOF_Group that contains the ID of equation numbers. When invoked this method sets that link for the DummyNode object.

virtual DOF_Group \*getDOF_GroupPtr(void);

Method which returns a pointer to the DOF_Group object that was set using setDOF_GroupPtr. If no pointer has been set a \(0\) is returned.

virtual int getNumberDOF(void) const;

Returns the result of invoking getNumberDOF() on its associated Node object.

virtual Vector &getMass(void) const;

Returns the result of invoking getMass() on its associated Node object.

virtual void setMass(Vector &mass);

Invokes getNumberDOF() on its associated Node object.

virtual const Vector &getCrds(void) const;

Returns the result of invoking getCrds() on its associated Node object.

virtual const Vector &getDisp(void) const;

Returns the result of invoking getDisp() on its associated Node object.

virtual const Vector &getVel(void) const;

Returns the result of invoking getVel() on its associated Node object.

virtual const Vector &getAccel(void) const;

Returns the result of invoking getAccel() on its associated Node object.

virtual const Vector &getTrialDisp(void) const;

Returns the result of invoking getTrialDisp() on its associated Node object.

virtual const Vector &getTrialVel(void) const;

Returns the result of invoking getTrialVel() on its associated Node object.

virtual const Vector &getTrialAccel(void) const;

Returns the result of invoking getTrialAccel() on its associated Node object.

void addUnbalancedLoad(const Vector &additionalLoad);

Returns the result of invoking addUnbalancedLoad() on its associated Node object.

virtual const Vector &getUnbalancedLoad(void) const;

Returns the result of invoking getUnbalancedLoad() on its associated Node object. The following commands do nothing, they just return.
