ODE solvers for time-dependent PDE software
Conference

OSTI ID:6078014
It is possible to list many of the features that are desirable or essential in ODE solvers that are to be used in the automated solution of time-dependent PDE systems. Many ODE solvers available today, including those in the ODEPACK collection, have been designed with just such features in mind. But they do not meet the demand completely, by any means. Some desired capabilities, including various sparsity structures, have not yet been included. Or it may be that individual capabilities of interest each appear in one or more solvers, but not all in a single solver. Greater interchangeability of modules would be helpful. With continued efforts in the development and use of modern algebraic system solvers and in modular software design, ODE solvers should continue to come closer to meeting the needs of PDE software.
