Bernatz (mathematics, Luther College, Iowa) introduces solution techniques of separation of variables, orthogonal eigenfunction bases, and Fourier solutions, as well as the following advanced numerical solution techniques for nonlinear problems: the finite difference method, the finite element method, and "the finite analytic method wherein separation of variables Fourier series methods are applied to locally linearized versions of the original partial differential equations.
The presentation will examine general requirements of analytical models, survey of currently available models (rings, membranes, shells and 3-D), numerical simulation techniques (including survey of numerical integration finite difference and finite element techniques, and recent applications to tire simulation), survey of available numerical simulation codes and a dynamic model.
Among their topics are elementary partial differential equations, finite difference methods for Poisson problems, the numerical solution of linear elliptic grid equations, adaptive multigrid methods for linear elliptic problems, and the adaptive integration of parabolic problems.
