On the coupling of uncoupled flow and transport solvers

The coupling of flow and transport solvers we are dealing with in this paper represents a whole intermediate processing step taking place between the two. We develop new techniques to ensure mass conservation of the transport while using totally different numerical schemes in the flow and in the transport solvers. We also present a method which allows the use of larger time steps for the transport computation than the one used for the flow leading therefore to faster computations and considerable reduction in disk space for the storage of flow data. These techniques are applied and tested in the numerical application of 2D and 3D problems.
