Hi all,

Can anyone tell me anything about the satisfaction of the Entropy condition by ENO schemes? I know that these schemes must satisfy the entropy condition, but I cannot see how that is done as part of a solution. I have seen some inequalities in text books which suggest you need to do a calculation on results to know if the solution is entropy satisfying. I want to know a priori. How can you ensure the "SCHEME" is ntropy condtion and ENO schemeentropy satisfying?

Can someone recommend a text or paper that deals with this?

Thanks.

Hi, The book "High-Order Methods for Computational Physics", T.J. Barth and H. Deconinck (editors) - published by Springer - includes two articles dealing with the ENO and WENO schemes. However, I'm not sure if they discuss about this issue.

Best regards

Hi,

Search the net for Engquist Osher and Sukumar Chakravarthy for ENO/WENO schemes. It's highly mathematical and one needs lot of patience to go through their papers.

The book is discontinued, and not available in my library. Do you know of any other references? Thanks for your help.

Try this ICASE report:

Chi-Wang Shu: ENO and WENO Schemes for Hyperbolic Conservation Laws, ICASE Report No. 97-65. (79 pages)

Thanks,

I've read it. Not alot on Entropy in there.....
