kei-tee Guest Posts: n/a	Hi,everyone. I use Roe scheme with MUSCL in low mach number, subsonic flow for high lift device analysis. I wonder Entropy fix technique & slope limiter of MUSCL is need or not in such case. Ofcourse, flow is shockfree. As far as my understanding, both methods are derivered from Riemann problem ,like shock wave. Are these are must or not? Please give me your opinion, Best regards. kei-tee.
