# chapter of the OOF2 manual.

# Define a new Field.  The available field classes are ScalarField
# (for scalars like Temperature) and TwoVectorField (for vectors like
# Displacement.  The 'Two' in 'TwoVectorField' refers to the number of
# in-plane components.  When OOF gets a third dimension, all
# VectorFields will have three components.)

Strawberry = problem.advertise(field.ScalarField('Strawberry'))

# Define a new Flux.  The available classes are VectorFlux (eg,
# HeatFlux, ElectricCurrent) and SymmetricTensorFlux (eg Stress).

Jam = problem.advertise(flux.VectorFlux('Strawberry_Jam'))

# Define a new Divergence Equation.  The equation equates the
# divergence of a given flux with some external forcing terms.  The
# external forces are specified by Material Properties.  The
# relationships between the Fields and the Flux are also given by
# Material Properties (ie, they're not specified here!).
