Abstract

Software for the solution of partial differential equations using adaptive refinement, multi-level solvers and parallel processing is complicated and requires careful design. This paper describes the design of such a code, PHAML. PHAML is written in Fortran 90 and makes extensive use of advanced Fortran 90 features, such as modules, optional arguments and dynamic memory, to provide a clean object-oriented design with a simple user interface.
