4. Functionality¶
The main functionality is handled with a PostProcessor
-instance, populated with several Field
-items.
The Field
-items added to the PostProcessor
can represent meta computations (MetaField
, MetaField2
) such as time integrals or time derivatives, restrictions or subfunction, or norms. They can also represent custom computations, such as stress, strain, stream functions etc. All subclasses of the Field
-class inherits a set of parameters used to specify computation logic, and has a set of parameters related to saving, plotting, and computation intervals.
The Planner
, instantiated by the PostProcessor, handles planning of computations based on Field-parameters. It also handles the dependency, and plans ahead for computations at a later time.
For saving purposes the PostProcessor also creates a Saver
-instance. This will save Fields as specified by the Field-parameters and computed fields. It saves in a structured manner within a specified case directory.
In addition, there is support for plotting in the Plotter
-class, also created within the PostProcessor. It uses either dolfin.plot or pyplot.plot to plot data, based on the data format.
