  author={Yuri Bazilevs and Victor M. Calo and Jennifer A Cottrell and John A. Evans and Thomas J. R. Hughes and Scott Lipton and Michael A. Scott and Thomas W. Sederberg},
We explore T-splines, a generalization of NURBS enabling lo cal refinement, as a basis for isogeometric analysis. We review T-splines as a surface design methodology and then develop it for engineering analysis applications. We test T plines on some elementary twodimensional and three-dimensional fluid and structural ana ysis problems and attain good results in all cases. We summarize current limitations and f uture opportunities.
