2. Fast Finite-Difference Solution of Biharmonic Problems.

Author

Timlake, W. P., Greenspan, D., and Schultz, D.

Subjects
*BIHARMONIC equations, *MATHEMATICAL analysis, *PARTIAL differential equations, *NAVIER-Stokes equations, *NUMERICAL analysis, *FLUID dynamics
Abstract

Setting the Reynolds number equal to zero, in a method for solving the Navier-Stokes equations numerically, results in a fast numerical method for biharmonic problems. The equation is treated as a system of two second order equations and a simple soothing process is essential for convergence. An application is made to a crack-type problem. [ABSTRACT FROM AUTHOR]
