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.
