A Spectral Difference Method Using Dubiner Polynomials
A Spectral Difference Method Using Dubiner Polynomials
We present a new Spectral Difference Method using Dubiner polynomials on triangles which unifies high order accuracy and simplicity. A corresponding exponential filter is used to avoid oscillations near discontinuous solutions. Furthermore, we focus on the edge detection approach in two dimensions in order to reduce the number of filtered …
