Pressure in fluid region
Hi everybody

I've been attempting to simulate an underwater explosion using the adiabatic bubble model, following the approach described by Tony Hirt in FSI-89-TN22. However, I'm having a hard time setting the pressure in the initial explosion gas bubble (PREG) to a different value than the initial void pressure (PVOID). It seems like PVOID is overriding PREG somehow.

I'm using v9.4.5 on a WinXP x64 machine. Any hints would be highly appreciated.

i am trying to simulate an underwater explosion.
I want to see how the shockwave behaves with a surface.

How did you generate your bubble model?
Did you use Fluent?

I am thinking about creating the bubble by generating a high energy source at a point in the domain.

I would really appreciate any kind of help you can provide.
