Algorithmic class for performing a static analysis using the displacement control method.
DisplacementControl is a subclass of StaticIntegrator, it is used to when performing a static analysis on the FE_Model using the displacement control method. In the displacement control method the displacement at a specified degree-of-freedom Uc is specified for each iteration. The following constraint equation is added to equation~staticFormTaylor} of the StaticIntegrator class:
[ Uc_n^{(i)} - Uc_{n-1} = Uc_n ]
where \(\delta Uc_n\) depends on \(\delta Uc_{n-1}\), the displacement increment at the previous time step, \(J_{n-1}\), the number of iterations required to achieve convergence in the previous load step, and \(Jd\), the desired number of iteraions. \(\delta //! Uc_n\) is bounded by \(\delta Uc_{min}\) and \(\delta Uc_{max}\).
\[ \delta Ucn = max \left( \delta Uc{min}, min \left( \frac{Jd}{J_{n-1}} \delta Uc{n-1}, \delta Uc{max} \right) \right) \]

Make required changes when a change in the domain occurs.
Is called by the Analysis object. Refer to the Analysis classes to see when it is invoked. To return \(0\) if successful, a negative number if not. This base class returns \(0\).
Reimplemented from XC::Integrator.
Reimplemented in XC::DistributedDisplacementControl.
|
virtual |
Receive the object.
Each object has to receive the data needed to be able to recreate itself in the new process after it has been sent through cp
. If the object is an aggregation containing other objects, new objects of the correct type can be constructed using #theBroker. To return 0 if successful or a -1 if not.
Implements XC::MovableObject.
Reimplemented in XC::DistributedDisplacementControl.
|
virtual |
Send the object.
Each object has to send the data needed to be able to reproduce that object in a remote process. The object uses the methods provided by cp
object to send the data to another channel at the remote actor, the address of the channel is set before this method is called. An object of similar type at the remote actor is invoked with a receiveSelf() to receive the data. Returns 0 if successful (successful in that the data got to the channel), or a - if no data was sent.
Implements XC::MovableObject.
Reimplemented in XC::DistributedDisplacementControl.

virtual |
When invoked causes the integrator object to update the DOF_Group responses with the appropriate values based on the computed solution to the system of equations object.
