Ph.D. positions in Computational Geometry and Mechanics at BYU

Two PhD positions in my research group are immediately available. Both positions involve the design, analysis, and implementation of numerical methods for computer aided design, analysis, and optimization with particular emphasis on complex multiphysics systems.

Isogeometric Analysis (IGA)

The aim of this post is to give a brief introduction to the recently emerged isogeometric analysis (IGA) which was presented in the seminal paper " Hughes, T.J.R.; J.A. Cottrell, Y. Bazilevs (2005). "Isogeometric analysis: CAD, finite elements, NURBS,exact geometry and mesh refinement". Comput. Methods Appl. Mech. Engrg. (Elsevier) 194: 4135–4195." IGA refers to a computational framework in which the basis functions used to represent the geometry in CAD are used for approximating the unknown fields in FEA. In this regard, IGA also employs the well known isoparametric concept.
