Investigation of stability and accuracy of high order generalized finite element methods
… to provide users with flexibility in choosing enrichments to approximate the target problem. The quality of the resulting approximation can be judged by the accuracy and its convergence rate, the conditioning and its growth rate. A major type of GFEM enrichment is the polynomial enrichment. …

Dimensionally reduced modeling and gradient-based design of microchannel cooling networks
… network. While previous IGFEM works are based on polynomial enrichment functions, we demonstrate the flexibility of the IGFEM by developing non-uniform rational B-splines (NURBS) enrichment functions for branched network of curved microchannels. We then develop a method to address the convergence …
