This book deals with all three most popular computational methods-CAE (finite elements, boundary elements, collocation methods) in a unified way.

It also bridges CAD with CAE. It includes applications to a broad spectrum of engineering and provides access to MATLAB codes with step-by-step tutorials.

We investigate the isogeometric analysis for surface PDEs based on the extended Loop subdivision approach. The basis functions consisting of quartic box-splines corresponding to each subdivided control mesh are utilized to represent the geometry exactly, and construct the solution space for dependent variables as well, which is consistent with the concept of isogeometric : Qing Pan, Timon Rabczuk, Gang Xu, Chong Chen.

This is due to the linearized quantities. We shall here not go in detail on how to derive the needed equations from Hooke’s law, but we present the notation used in the formulation of the isogeometric analysis. The notations used, takes inspirations from the book by Hughes. The book shows how the isogeometric philosophy can be implemented and how its benefits can be maximised with a minimum of user effort.

Using several examples, ranging from potential problems to elasticity, it demonstrates that the isogeometric approach results in a drastic reduction in the number of unknowns and an increase in the quality of.
