| enum | ReturnType { Ok, NotDefined, BadDependency, NotConverged, Failed } |
| The computation of, say, the Newton direction in computeNewton() may fail in many different ways, so we have included a variety of return codes to describe the failures. Of course, we also have a code for success. More... | |
Abstract interface class for continuation strategies.
AbstractStrategy defines an abstract interface for continuation strategies. This interface is used by the LOCA::Stepper to manipulate continuation groups in a consistent manner. It defines a number pure virtual methods that all continuation groups must implement.
|
pure virtual |
Perform any postprocessing after a continuation step finishes.
The stepStatus argument indicates whether the step was successful.
Implemented in LOCA::MultiContinuation::ExtendedGroup.
|
pure virtual |
Perform any preprocessing before a continuation step starts.
The stepStatus argument indicates whether the previous step was successful.
Implemented in LOCA::MultiContinuation::ExtendedGroup.
|
pure virtual |
Sets tangent to predictor.
This is required by MF which takes the tangent space, orthogonalizes it, and then sets it back in the group.
Implemented in LOCA::MultiContinuation::ExtendedGroup.
