Question about WENO limiterHi.
These days I'm studying WENO limiter through following papers. ("Runge-Kutta discontinuous Galerkin method using WENO limiters" and "RKDG method with WENO type limiters and conservative interfacial procedure for one-dimensional compressible multi-medium flow") I have one question. There are WENO reconstruction in the method. (ex) if we use k(the order of polynomial in DG)=1, we construct linear reconstruction polynomials p(x) and a second degree reconstruction polynomial q(x). In this case polynomial p(x) can be obtained easily. But polynomial q(x) is very complex to obtain. I want to obtain polynomial q(x). I would appreciate it if anyone give me some comments. Thanks!! |
