Isogeometric Analysis: Integrating Design and Analysis (IGA 2014) will be held
January 8-10, 2014 in Austin, Texas, USA.

Geometry is the foundation of analysis yet modern methods of computational geometry have until recently had very little impact on analysis.  The reason may be that Finite Element Analysis (FEA), as we know it today, was developed in the 1950's and 1960's, before the advent and widespread use of Computer Aided Geometric Design (CAGD), which occurred in the 1970's and 1980's.  The CAGD - FEA interface gives rise to many problems.  Perhaps the most significant of all is the problem of translating CAGD files into analysis-suitable FEA geometry and meshing, reputed to take 80% of overall analysis time for complex engineering designs.  The approximate, polynomial-based geometry of FEA also creates difficulties in modeling sliding contact, flows about aerodynamic shapes, buckling of thin shells, etc.  It would seem that it is time to look at more powerful descriptions of geometry to provide a new and more efficient basis for analysis.  An attempt to address these issues and improve on FEA has led to the introduction and development of Isogeometric Analysis, in which a single geometric representation is utilized for design and analysis.  Among the approaches that have been proposed, those that have demonstrated the most potential so far are Subdivision Surfaces, NURBS, and T-splines.  NURBS are the industry standard for CAGD systems used in engineering design.  NURBS-based isogeometric analysis has already been applied to fuids, structures, fluid-structure interaction, phase-field modeling, electromagnetics, shape and topology optimization, material modeling (e.g., implicit gradient damage models), discrete and diffuse modeling of crack propagation, etc.  T-splines, which are a generalization of NURBS that allow efficient local refinement while maintaining higher-order continuity and exact geometry, have recently attracted increasing attention.  The purpose of this workshop is to bring together experts in geometry and analysis interested in the development of the new generation of analysis procedures on modern methods of computational geometry.
