A depth-averaged equation set is solved to simulate Mobile Bay circulation. A semi-implicit algorithm with an alternating-direction-implicit technique is employed to perform numerical computations on a staggered Cartesian grid mesh that covers the Mobile Bay area. The simulation results include effects from the four major rivers around Mobile Bay. Flow patterns and elevation contours are shown during flood and ebb tides. Velocity vectors and particle tracers are used to indicate the flow patterns and related transport of Mobile Bay circulation.

Fokker-Planck (FP) codes have become useful tools for modeling nonlocal heat-transport phenomena in laser-produced plasmas. Several possible simplifications to the FP equation as well as different numerical techniques available for its solution are investigated. The most robust and efficient approach is found to involve the diffusive approximation of the FP equation and the alternating-direction-implicit method of solution. The SPARK FP code, which has been developed along these principles, is described in detail. It incorporates fluid ions and solves for transport on either a two-dimensional Eulerian grid or a one-dimensional Lagrangian grid. Sample simulation results are presented, together with a discussion of possible improvements to the code.
