Drawing is one of the elementary human abilities. It requires practice. But one must not draw with the skill of a Leonardo da Vinci or an Albrecht Dürer to be able to create drawings that are informative, aesthetic, and a joy to others. The drawing of geological objects is at a level that anyone can reach with a little practice and by following a few rules (Figure 1.1).<...>

Numerical modeling is the process of obtaining approximate solutions to problems of scientific and/or engineering interest. The book series addresses novel mathematical and numerical techniques with an interdisciplinary emphasis that cuts across all fields of science, engineering and technology. It focuses on breakthrough research in a richly varied range of applications in physical, chemical, biological, geoscientific, medical and other fields in response to the explosively growing interest in numerical modeling in general and its expansion to ever more sophisticated physics. The goal of this series is to bridge the knowledge gap among engineers, scientists, and software developers trained in a variety of disciplines and to improve knowledge transfer among these groups involved in research, development and/or education. <...>
