No-reflection Boundary conditions for v7.3.1
 
1 Attachment(s)
Hi SU2 users/developers:

Is there any non-reflection boundary conditions can be used in v7.3.1? Currently I am working on a 2D supersonic simulation and wish to eliminate the shock reflection on both top and bottom boundaries (showed in attached snapshot), what should I do with this? Now both boundaries are set as far field.

Maybe you can try this tutorial as a starting point, which uses Riemann BC for inlet and outlet:
