ENO / WENO scheme

phy4me · October 26, 2010, 07:07

Hi all Would somebody could tell me how can I set up a procedure ENO / WENO end to increase the order of a Roe scheme. any helps are welcome ( code, docs, contact authors ... ) Thanks in advance

Hi

You can refer the paper of Osher and shu where in they have described clearly how to proceed for weno schemes. You need solve the system of equations as in compact schemes to get the approximate values at the faces.

Hi,
Can you give me a link of this article ? have you used WENO in your works ?

Thanks for you

You can find information about how to use WENO in the following two books:

Shu C.W. (1999), High-Order ENO and WENO Schemes for Computational Fluid Dynamics, in "High-ORder MEthods for Computational Physics", Lecture Notes in Computational Science and Engineering Vol. 9, Springer.
http://books.google.com/books?id=icd...tially&f=false

Osher S., Fedkiw R. (2002), Level Set Methods and Dynamic Implicit Surfaces, Springer.

Thank you so mush for your reply valgrinda and this links.

Unfortunately google does not show good part of his tenth book, in fact I just need to understand the principle of the method and the algorithm and after that will be easy because I have mastered my code perfectly.

None of you has worked on the shallow water equations ?
