Object-oriented Fortran 90 P-adaptive finite element method

Over the last decade, there has been an increased awareness of the benefits of employing Object-Oriented (OO) design and methodologies for development of software. Among the various languages available for OO development, Fortran 95 has some clear advantages for scientific and engineering programming. It offers features similar to other OO languages like C++ and Smalltalk as well as extensive and efficient numerical abilities. This paper will describe the OO design and implementation of P-adaptive finite element analysis (FEA) using Fortran. We will demonstrate how various OO principles were successfully employed to achieve greater flexibility, easier maintainability and extensibility. This is helpful for a complex program like an adaptive finite element implementation.
