Partial differential equations and finite element method. (English) Zbl 1092.65080

In the book an introduction in the analysis and numerical solution of partial differential equations (PDEs) is presented. In Chapters 1-4 an introduction into the theory of PDEs is given and the basic concept of the finite element method is described. Especially, nodal and hierarchical approaches for the construction of higher-order elements are discussed. Chapter 5 is devoted to the numerical solution of systems of ordinary differential equations arising from the semidiscretization of time-dependent PDEs.
In Chapter 6 the numerical solution of fourth-order problems (beam and plate bending problems) is explained. The mathematical model is described, the weak formulation is given and the unique solvability is proved. Again lowest-order and higher-order approximations are used in the finite element discretization. In Chapter 7 the numerical solution of problems of electromagnetics is discussed. A detailed description of the mathematical models is given and the concept of modern edge elements is explained.
Appendix A contains the basics of functional analysis and linear algebra which are necessary for understanding the theory and numerical treatment of partial differential equations. In Appendix B some finite element software is described and numerical examples arising from practical problems are reported. The book is useful for all people who are working in disciplines of computational engineering.
