| Sumari: | An efficient B-spline method for the construction of a piecewise polynomial velocity representation from a given set of normal fluid fluxes is described for steady incompressible flow in three dimensional rectangular regions. The fluxes should be defined across the face-centres of a cartesian tensor product mesh. The proposed spline representation interpolates the given fluxes exactly and also enables the normal fluid velocity to be set identically to zero across or around the surfaces of an arbitrary number of rectangular regions lying in specified planes. |
