While 2021 continued to present unique challenges and unprecedented disturbances, we hope that you found our customer support, on-demand webinars, web-based training services and overall experience with our team to be refreshingly positive. Happy Holidays from all of us at ESRD, and we hope you'll check out our year-end summary!
Contrary to various claims, IGA is not a new paradigm in the numerical approximation of partial differential equations; it is simply an alternative implementation of the p-version of the finite element method. IGA is one possible implementation of the p-version of the finite element method. Its distinguishing features are: (a) it retains the CAD geometry, (b) the basis functions are the same as those used for CAD representation, typically B-splines or NURBS, and (c) it provides for the enforcement of the inter-element continuity of the derivatives of the basis functions.
