Igatools: An Isogeometric Analysis Library [PDF]
SIAM Journal on Scientific Computing, 2015 Summary: We present the design of an object oriented general purpose library for isogeometric analysis, where the mathematical concepts of the isogeometric method and their relationships are directly mapped into classes and their interactions. The encapsulation of mathematical concepts into interacting building blocks gives flexibility to use the ...

Construction of approximate C1 bases for isogeometric analysis on two-patch domains [PDF]
arXiv.org, 2021 In this paper, we develop and study approximately smooth basis constructions for isogeometric analysis over two-patch domains. One key element of isogeometric analysis is that it allows high order smoothness within one patch.
