model.sol().create(<tag>) adds a solver sequence to the model.

model.sol().create(<tag>,<studytag>) adds a solver sequence to the model. The constructor adds one feature of the type StudyStep to the solver sequence with the tag <studytag>. This StudyStep feature is connected to a study step (see model.study()).

model.sol().create(<tag>,<studytag>,<varstag>) adds a solver sequence to the model. The constructor adds one feature of the type StudyStep with the tag <studytag> and one feature of the type Variables with the tag <varstag> to the solver sequence.

model.sol().remove(<tag>) removes a solver sequence from the model.

model.sol(<tag>).create(<ftag>,<oper>) creates a solver feature. Each solver feature is a solver operation.

 model.sol(<tag>).feature().remove(<ftag>) removes the solver feature <ftag>.

 model.sol(<tag>).feature(<ftag>).set(property,<value>) sets the property property for the feature <ftag>.

model.sol(<tag>).feature(<ftag>)).getAllowedPropertyValues(property) returns the set of allowed values for a property if the set is a finite set of strings; otherwise, it returns null.

model.sol(<tag>).attach(<stag>) attaches a solver sequence with tag <tag> to a study with tag <stag>, which makes it visible under that study.

model.sol(<tag>).copySolution(<ctag>) copies the solution data associated with the solver sequence <tag> to a new solver sequence <ctag>. The features are not copied.

model.sol(<tag>).createAutoSequence(<stag>) creates a solver sequence of features automatically from the study <stag>. The sequence of study steps are used as input to the sequence generation algorithm but also the physics used in the study steps are used to automatically adopt the solver settings.

model.sol(<tag>).createSolution() creates a solution object from one or more set operations (setU(..), ...), see Solution Creation for details.

model.sol(<tag>).updateSolution() updates a solution data associated with the solver sequence to make it consistent with the current model.

model.sol(<tag>).isEmpty() is true if there is no solution data or if all solution data has been cleared.

model.sol(<tag>).isInitialized() is true if the solution is a valid (initialized) object. Even if the solution has been cleared, isInitialized is true (use isEmpty to check for cleared solution data).

 model.sol(<tag>).run(<ftag>) runs the features for a solver sequence up to and including the feature <ftag>.

model.sol(<tag>).runFrom(<ftag>) runs the features for a solver sequence from and including the feature <ftag>.

 model.sol(<tag>).runFromTo(<ftagstart>,<ftagstop>) runs the features for a solver sequence from and including the feature <ftagstart> to and including the feature <ftagstop>.

model.sol(<tag>).runAll() and  model.sol(<tag>).run() run all the features for a solver sequence.

 model.sol(<tag>).continueRun() continues to run a solver sequence.

Assume that a study st1 represents one stationary study step with the tag stat1 for some equations.

Assume that a second study step with frequency response is added to the study with tag freq1 and that you want to make a frequency sweep from 10 to 1000 using the parametric solver and the solution above as the linearization point (bias solution).

At this point the solution s is associated to the study step freq1 (but it depends indirectly on the bias study step stat1 as well).
