Abstract

Continuing the discussion of the multi-adaptive Galerkin methods {$\mathrm{mcG}(q)$} and {$\mathrm{mdG}(q)$} presented in [A. Logg, SIAM J. Sci. Comput., 24 (2003), pp. 1879--1902], we present adaptive algorithms for global error control, iterative solution methods for the discrete equations, features of the implementation Tanganyika, and computational results for a variety of ODEs. Examples include the Lorenz system, the solar system, and a number of time-dependent PDEs.
