The dual reciprocity method provides a boundary integral technique for solving
boundary value problems with source terms.
As such it is an attractive
alternative to techniques such as finite differences or finite elements.
Unfortunately, normal derivative values are frequently calculated much less
accurately then are function values.
Various approaches have been proposed in
other boundary element situations viz multiple nodes, discontinuous elements
and the gradient method.
The gradient method works particularly well with the
dual reciprocity method and gives improved flux values over a wide variety of
linear and non-linear problems.
The boundary element method for the solution of homogeneous elliptic
boundary-value problems, in which the boundary-value problem is replaced by
