Invited Paper Time-dependent Stokes flow for interior and exterior domains via dual reciprocity boundary element method H. Power", P.W.

In order to satisfy the re- quired asymptotic behavior at infinity in the case of an unbounded domain, special considerations have to be taken into account in the formulation of the Dual Reci- procity Method.
