.. py:class:: CoeffSystem(subproblems, dtype)

   Representation of a collection of fields that don't need to be transformed,
   and are therefore stored as a contigous set of coefficient data for
   efficient pencil and group manipulation.

   :Parameters: * **nfields** (*int*) -- Number of fields to represent
                * **domain** (*domain object*) -- Problem domain

   :ivar data: Contiguous buffer for field coefficients
   :vartype data: ndarray

   .. py:attribute:: data


.. py:class:: FieldSystem(fields, subproblems)



   Collection of fields alongside a CoeffSystem buffer for efficient pencil
   and group manipulation.

   :Parameters: * **field_names** (*list of strings*) -- Names of fields to build
                * **domain** (*domain object*) -- Problem domain

   :ivar data: Contiguous buffer for field coefficients
   :vartype data: ndarray
   :ivar fields: Field objects
   :vartype fields: list
   :ivar nfields: Number of fields in system
   :vartype nfields: int
   :ivar field_dict: Dictionary of fields
   :vartype field_dict: dict


   .. py:method:: gather()

      Copy fields into system buffer.



   .. py:method:: scatter()

      Extract fields from system buffer.
