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

Two references may help you about MUSCL:

1. W. Anderson et al, AIAA P 85-0122, 1985.

2. L. Yuan, JCP Vol. 177, p.138, 2002.

See also an article:

A. Gilmanov. A Local Characteristic Approach in High-Order Differencing // J. Computational Mathematics and Mathematical Physics (Russian Journal). 2000. Vol. 40. No. 4. P.529-533 (in English).

A limiter I use is very good.
