  In this study, we presented the high-order fundamental solutions and general
solutions of convection-diffusion equation. To demonstrate their efficacy, we
applied the high-order general solutions to the boundary particle method (BPM)
for the solution of some inhomogeneous convection-diffusion problems, where the
BPM is a new truly boundary-only meshfree collocation method based on multiple
reciprocity principle. For the sake of completeness, the BPM is also briefly
described here.
