Hi everyone,
I am wondering if anyone knows what nonreflective boundary condition has been implemented in ANSYS CFX. As it is a beta feature it seems as there is no documentation, not even who developed the boundary condition. Any guidance would be greatly appreciated. |

Good question, you should ask ANSYS support that question.

Hi Thomas,
I am also interested in the non-reflective boundary conditions due to a current project. So far I found out that there are two different non-reflective boundary conditions in CFX: one for inlets, outlets and openings and one especially for openings (absorbing layer). Furthermore I found a thesis in which the first boundary condition was described and used. According to this thesis the boundary condition is based on a work by Poinsot and Lele and there is a validation report by Zwart and Abshoff. I hope this helps you. I would also appreciate any further information. thesis: Computation of the Thermoacoustic Driving Capability of Rocket Engine Flames with Detailed Chemistry by Attila Lehel Török (found at google scholar) paper: Boundary Conditions for Direct Simulations of Compressible Viscous Flows by Poinsot and Lele (found at google scholar) Validation report: Non-reflective Boundary Conditions in CFX-5 by Zwart and Abshoff Greetings! |

Thank you for the response so far!
I am currently trying to get in contact with Ansys support but I have to go through the University which makes it a bit of a complicated process. Hence I asked here but if I get an answer I will post it. The literature mentioned is great for the mean time. Unfortunately it seems as the Ansys validation report is not publicly available. |
