Meet the editors

Dr. Jan Valdman is an associate professor of applied mathematics at the Faculty of Science, University of South Bohemia in České Budějovice and a researcher at the Institute of Information Theory and Automation of the Czech Academy of Sciences in Prague. He obtained his MSc degrees from the Mathematical Research Institute in Utrecht, the Netherlands, and the University of West Bohemia in Pilsen, Czech Republic in 1998. He graduated from

the University of Kiel, Germany with his PhD thesis on modeling of elastoplasticity in 2002. After spending further years at several foreign institutions (Linz, Bergen, Reykjavik, and Leipzig), he returned to Czech Republic and finished his habilitation at the Technical University of Ostrava in 2011. His areas of interest include computational nonlinear mechanics of solids and aposteriori error estimates for nonlinear problems. He has published several vectorized finite element codes in MATLAB.

Dr. Leszek Marcinkowski is an associate professor of applied mathematics at the Faculty of Mathematics, Informatics, and Mechanics, University of Warsaw. He obtained his MSc degree in 1994, his Ph.D. degree in 2000, and his habilitation in 2010 from the University of Warsaw. All degrees were obtained with distinctions. His Ph.D. thesis was on parallel solvers for partial differential equations discretizations. Later he was a post-doc-

toral fellow in the Department of Computer Science of the University of Colorado at Boulder, USA. He visited many foreign institutions, including the University of Colorado, Lawrence Livermore National Laboratory, and the University of Bergen, for shorter research visits. His research areas are focused on discretization methods and parallel solvers for partial differential equations. In particular, he is interested in discretizations built on nonmatching grids and domain decomposition methods.

Preface

The idea of editing this book together came at the conference PPAM 2019, in September 2019 in Białystok, Poland, which both editors attended. The actual work started in November 2019 and took a bit longer due to Covid-19; however, our online cooperation did not stop our activities. The general aim of this book was to present selected chapters of two types: chapters with more focus on modeling with some necessary simulation details and chapters with less focus on modeling but with more simulation details. During the selection process, many contributions were received, but some had to be rejected. These were mostly too theoretical and missing explanations of the algorithms or simulation details. Finally, we present eleven chapters divided into two sections according to areas of their applications:

We hope our book entitled "Modeling and Simulation in Engineering - Selected Problems" will serve as a useful reference to students, scientists, and engineers. We are thankful to each author for the technical effort presented in each book chapter

Our biggest thanks go to Ms. Dolores Kuzelj, Author Service Manager from

IntechOpen, who instructed us through all stages of the editorial process. Together,
