Classes for systems of coefficients/fields.

Module Contents

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

Variables:

data (ndarray) – Contiguous buffer for field coefficients

get_subdata(sp, ss=None)
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

Variables:

  • data (ndarray) – Contiguous buffer for field coefficients

  • fields (list) – Field objects

  • nfields (int) – Number of fields in system

  • field_dict (dict) – Dictionary of fields

gather()

Copy fields into system buffer.

scatter()

Extract fields from system buffer.
