non-reflecting boundary condition in Application/NS/naca0012 case #45

Closed Cornelii closed 1 year ago

Cornelii commented 1 year ago

Hello.

First of all, Thank you for your works.

I want to get some guidance about non-reflecting boundary condition.

When running naca0012 examples, which you provide at Application/NS, it showed like boundary-induced oscillating, ended up going to divergence.

Could you check the above case to make it converged.

On the other hand, from references mentioned on the paper, i guess the kind of characteristic terms, which is in (ubou) , need to be within flux (fbou) in the form of boundary flux.

Can i get any indicates or references regarding why you put "A" (jacobian) in the (ubou) not (fbou)

Thank you.

P.S I found some tiny bug at execution on gpu, after i tested i am going to post issue about that.
