Abstract
For convection-diffusion equations and generalised axisymmetric Poisson
equations (GASPEs), we derive a new DRM (dual reciprocity method) for-
mulation. In comparison with the traditional scheme for these problems,
we find that the new formulation is easier and more compact, and saves
some computational effort since the new scheme "shifts" the burden of ma-
trix multiplications to the particular solutions. For GASPEs, however, it is
quite difficult to find these particular solutions for commonly-used RBFs
(radial basis functions), but we propose a remedy for this situation. Two
examples demonstrate the approach.
