Question Boundary condition for pressure wave simulation

Hi everyone,

I'm working in a simulation of an exploding tank:
The domain consists in two concentrical circles. The small one, in the middle, represents the tank and is set as pressure-inlet, with an UDF.

The goal is to see how the wave moves over time.

My concrete question is what boundary condition should i use for the outlet (bigger circle).

My first idea was to use pressure-outlet with gauge pressure = 0, but i'm not sure if that's OK, because that pressure may change when the wave arrives.

I can't use outflow (according to the help, it can't be used with pres-inlet)
Maybe far-field?

I hope someone can help me!
Thanks in advance and please excuse my english.
