    abstract     = {Summary: We investigate the approximation error of mapped NURBS spaces, such as those used in isogeometric analysis in accordance to the isoparametric paradigm. We extend the results of [the first author et al., Numer. Math. 118, No. 2, 271--305 (2011; Zbl 1222.41010)] to the case of anisotropic meshes, such as those needed in the presence of boundary layers. The theoretical results cover anisotropic $h$-refinement and are supported by numerical tests involving different geometries.},
