Default User Defined Non Reflecting Boundary Condition
Posts: n/a
HI folks

I simulate a case with a shockwave in water. With 6.2.5 segregated solver (the new solution from fluent) or a udf-based 6.1.22 coupled imp solution. In both the problem is 2d, dp, compressible, unsteady. All shockwaves reflecting at the pressure-outlet boundary. Now I need to programm a NRBC (nonreflecting-BC) with UDF. My idea is that I read the Face-Pressure out in every BC-Face, invert it and write back to clean the reflection. I just need to see what happen in the closed case and each wave which leaves the boundary should not get reflected.

Thx for ur ideas Christian Tenger, Fachhochschule Biel Schweiz

A simple can you set the value of the pressure you want? i'm really interested the way you do it. thanks Luca
