Instability in temperature contour with ROE scheme #2490

Hi, I tried to run some simulation on onera M6 wing with different numerical settings to find what works best for transonic regime flow, when experimenting with numerical setup I observe flow instabilities on wing when using ROE scheme, instabilities that are not present in case that uses JST scheme.

Here is a plot of temperature distribution at the middle of wing

And here is a link to archive with both cases. I will try with some other schemes but would appreciate the help for making ROE scheme work as JST.

Thanks.
