Hello,

I'm trying to model the interaction of a shock wave in gas and a cylindrical object. There has to be a partial reflection but so far I fail to get that in my solutions. I am total noob to openFOAM, so I started with shockTube tutorial and changed mesh accordingly. I tried both sonicFoam and rhoCentralFoam, but neither gave me what I wanted.

Here's closeup of my mesh near said cylinder just in case it matters somehow:


And here are my results:
t=0


t=0.003


t = 0.006


As you can see, there's no reflection of the wave where in theory should be some.

Source file are
controlDict

fvSchemes

fvSolutions

So what should I do? Am I using right solvers and what seems to be the problem?

Thanks in advance.

I found this thread in similar, gonna check if changing boundaries on the cylinder works.
