I want to simulate a pressure equalization. For an easy example of my problem, you can look at the picture below.
For t=0 the Chamber 1 has a pressure of 8bar and the chamber 2 a pressure of 1bar.
The Gas is Air and when the simulation starts at Timestep one, the Membrane collapse immediately. Afterwards
the pressure equalization starts.
It is a 3D-Simulation with a more difficult geometry as in the picture
My Problem: How can i build a Membrane which collaps immediatly ?
Thanks in advance,

If the membrane can be assumed to fail instantly and with no effect on the flow just use an interior zone and read the section on Patch (Initialisation).

Thank you for your help.
Now i want to simulate the pressure shock which occure in the system.
Do you think i have to use the density-based or the pressure-based solver?
The Fluid is air as ideal gas so it is compressible.
Thank you in advanve

Pressure based is good to about 2-3Ma, much over that and density based may be better.
