Finite Elements for Fluid Dynamics. Supercritical Design
Abstract
The mathematical modeling of a physical continum by a set of first- order partial differential equations is commonly redundant, i.e., it includes more equations than unknowns. A simple analysis gives the reduced set, which fully determines the field quantities satisfying appropriately prescribed initial and boundary conditions. An algebraic look at the system provides the appropriate choice for descretization, which is a necessary condition for solvability and stability. The same is tried for a number of variational representations of the field in terms of primitive variables. A few of the latter formulations are new. (Author)
