We present an explicit fourth-order compact ®nite dierence scheme for approximating the threedimensional convection±diusion equation with variable coecients. This 19-point formula is de®ned on a uniform cubic grid. We compare the advantages and implementation costs of the new scheme with the standar

Indeed it may well be that the deficiencies reported here do not appear in any important problem of purely recirculating flow, since such problems IRAD YAVNEH are ill-posed in the limit of vanishing viscosity unless the Department of Computer Science integral of the right-hand side function along each closed

## Abstract A class of higher order compact (HOC) schemes has been developed with weighted time discretization for the two‐dimensional unsteady convection–diffusion equation with variable convection coefficients. The schemes are second or lower order accurate in time depending on the choice of the
## Abstract The value of a contingent claim under a jump‐diffusion process satisfies a partial integro‐differential equation. A fourth‐order compact finite difference scheme is applied to discretize the spatial variable of this equation. It is discretized in time by an implicit‐explicit method. Mea
