This book focuses on the geometrycreation techniques for use in finite element analysis. Examples are providedas a sequence of fin designs with progressively increasing complexity. A finwas selected as it is a feature widely employed for thermal management. As thecontent progresses, the reader learns to create or import a geometry into a FEMtool using COMSOL Multiphysics®. The fundamentalsmay also be applied to other commercial packages such as ANSYS® or AbaqusTM. The content can be utilized ina variety of engineering disciplines including mechanical, aerospace,biomedical, chemical, civil, and electrical. The book provides an overview ofthe tools available to create and interact with the geometry. It also takes abroader look on the world of geometry, showing how geometry is a fundamentalpart of nature and how it is interconnected with the world around us. Features:Includes example models that enable the reader to implement conceptualmaterial in practical scenarios with broad industrial applicationsProvides geometry modeling examples created with built in features of COMSOLMultiphysics® v. 5.4 or imported from other dedicated CAD toolsPresents meshing examples and provides practical advice on meshgenerationIncludes companion files with models and customapplications created with COMSOL Multiphysics® ApplicationBuilder.
