Prof. P.G. Thomsen of this department will speak on ``Semi Implicit Runge Kutta Methods, Implementation, Part 2.'' TIME: 3:30 PM ROOM: MC 5097 ABSTRACT In this second part the emphasis will be on implementa- tion features, covering the following subjects - solution of nonlinear systems of equations - prediction of initial vectors for iteration - convergence-, stepsize- and error control - choice of starting stepsize. The program SIMPLE is a research code that has been develop to test our ideas. The code can be used for any SDIRK-method and has been used to give practical experience with our design parameters.
