Computational methods in fluid flow

Powerful computational techniques are available for the analysis of coupled flow deformation and transport problems. Domain methods are capable of accommodating irregular and heterogeneous geological bodies represented by complex constitutive models. Finite element methods represent the most powerful domain based method where tensoral quantities such as stresses and deformations are to be included. Depending on the particular geological system or process, some aspects of the coupling between competing processes may be either weakly present or absent. In either case a reduced set of equations describing the system will suffice. The form of the equation set may be determined from the maximum set following deletion of the absent coupling and used to advantage. -from Author
