limiters
 
Hi,

For the extension of Godunov scheme to second order it's necessary to us a limiter for limiting the nonphysical oscillations, I tested two types of limiters, Minmod is diffusive and Vanalbada generate some oscillations, I request if anyone know other limiters better

thanks. EMCA

Dear EMCA,

You can tru out Roe's superbee and/or Venkatakrishnan limiter. Tha latter is more popular among the CFD community.

Hope this helps

Regards.

Ganesh
