This book consists of selected peer-reviewed papers presented at the NAFEMS India Regional Conference (NIRC 2018). It covers current topics related to advances in computer aided design and manufacturing. The book focuses on the latest developments in engineering modelling and simulation, and its application to various complex engineering systems. Finite element method/finite element analysis, computational fluid dynamics, and additive manufacturing are some of the key topics covered in this book. The book aims to provide a better understanding of contemporary product design and analyses, and hence will be useful for researchers, academicians, and professionals. 

Dr. Chenfeng Li obtained his PhD in computational engineering (Swansea University), Masters in solid mechanics (Tsinghua University), and his Bachelors in engineering mechanics (Tsinghua University). Since 2013, he has been working as an associate professor at the Civil & Computational Engineering department, College of Engineering at Swansea University. His research is largely centered around computational science and engineering, with a special focus on stochastic modeling and its applications in energy, environmental and biomedical engineering; and physical modeling for graphics applications. He develops novel probabilistic models that allow accurate quantitative measurement and description of various practical random media that are non-Gaussian, non-stationary and nonlinear. Dr. Chenfeng also develops efficient numerical simulation techniques that can analyze and evaluate the uncertainty propagation through complex physical and engineering systems, which can guide the associated risk assessment and management.

Dr. U. Chandrasekhar is a scientist and academician with more than three decades of experience in research and project management. He received his bachelors from NIT Surathkal, Karnataka, and his masters from IIT Madras in mechanical engineering. He received his PhD from VTU for his research in additive manufacturing carried out at the Defense Research and Development Organisation (DRDO). He also hold an advanced diploma in management. Currently, he is the pro Vice-Chancellor of Vel Tech University. His areas of research include mechanical analysis of aero gas turbine engine modules, additive manufacturing, micro aerial vehicles, and sensors for harsh environments. He received a Gold Medal from the former President of India Dr. APJ Abdul Kalam for his academic achievements. After serving the Ministry of Defence in several capacities, he became Additional Director, DRDO in 2010. He set up India's first-ever rapid prototyping laboratory at GTRE, Bangalore. During his tenure at DRDO, he carried out several technology development projects and also led a senior group of scientists in Moscow during the testing phase of a developmental aero gas turbine engine. He received commendation medal from the Scientific Advisor to the Defence Minister in recognition of his contributions to rapid prototyping of complex aeronautical systems.

Dr. Godfrey Onwubolu holds a Bachelors in engineering (University of Benin), a Masters in mechanical engineering (Aston University), and a PhD in computer-aided design (Aston University). He is internationally recognized for his work in inductive modeling, especially in Europe, where he gives public lectures and examines doctoral theses on the subject. He is currently the lead researcher at Sheridan College in applying this technology to the joint Sheridan-Nexflow project for studying the behaviours of Nexflow air products based on their operational parameters. He continues to use his expertise in the domains of computer-aided design, additive manufacturing, and inductive modeling to impart knowledge to students as an engineering and technology educator, and to advance productivity in the manufacturing industry sector in Canada and other countries.
