MUSCL limiters????
I wrote an Euler code it uses Van leer /Steger warming as well as Roe scheme...I added the MUSCL type limiter....Im having slow convergence somehow and after certain numerical experimentations I discovered that the MUSCL has something wrong...Im wondering wether I should set the limiters to zero at the boundaries to resolve this problem....any suggestions???

hi
have a look to chap. 13 & 14 in Toro's book. the best to use is SUPEREBEE limiter. anyway, the book is Riemann solvers and numerical methods for fluid dynamics E. F. Toro; Springer

Two references may help you about MUSCL:
1. W. Anderson et al, AIAA P 850122, 1985. 2. L. Yuan, JCP Vol. 177, p.138, 2002.
