9 Matrix-Free Iterative Solution Procedure for Finite Element Problems

9.1 INTRODUCTION

In this chapter, we present some numerical techniques implemented in our computational systems intended to simplify the FE coding. They are related to matrix assembling and solving. Initially, we considered that the main ideas were original since their development and implementation were put together by us without any support from previous works. We proceeded with along literature search and did not find any similar work. We also discussed the subject with colleagues who have along experience with FE techniques and came to an identical conclusion and, therefore, we published three papers on this subject [13]. However, later, it was revealed that some ...
