Module esys.escript.linearPDEs

The module provides an interface to define and solve linear partial differential equations (PDEs) within escript. linearPDEs does not provide any solver capabilities in itself but hands the PDE over to the PDE solver library defined through the Domain of the PDE. The general interface is provided through the LinearPDE class. The AdvectivePDE which is derived from the LinearPDE class provides an interface to PDE dominated by its advective terms. The Poisson, Helmholtz, LameEquation, AdvectionDiffusion classs which are also derived form the LinearPDE class should be used to define of solve these sepecial PDEs.
Classes
AdvectivePDE In cases of PDEs dominated by the advection terms B and C against the adevctive terms A up-winding has been used.
Helmholtz Class to define a Helmhotz equation problem, which is genear LinearPDE of the form
LameEquation Class to define a Lame equation problem:
LinearPDE This class is used to define a general linear, steady, second order PDE for an unknown function u on a given domain defined through a Domain object.
PDECoefficient A class for describing a PDE coefficient
Poisson Class to define a Poisson equation problem, which is genear LinearPDE of the form

Exceptions
IllegalCoefficient raised if an illegal coefficient of the general ar particular PDE is requested.
IllegalCoefficientValue raised if an incorrect value for a coefficient is used.
UndefinedPDEError raised if a PDE is not fully defined yet.
