hi,

I am trying to write a 5th order FD ENO code. I managed to write the 3rd order ENO but I am having problems extending it to the 4th order and beyond. (I have oscillations and spikes in the solution) Currently, I am solving only the advection and burgers equation.

If anyone has an idea what could be wrong please let me know... If you have ENO code that you can share please do so.

thank you,

Vinod Venugopalan

I do not know which kind of ENO method are you using but it is nornal to have this oscillations with high orders in normal ENO, try using WENO or MPWENO instead which give better results
