Urgent,Shock tube simulation
 
Hello,
I want to simulate a shock tube problem in CFX, which the domain is initially divided into tow sub domain and each domain has two different gases with different states of pressure and temperature . At time t=0 , the diaphragm is removed and gases starts to interact. I have a problem in initialization of these two different domains. I would be appreciated if someone help me?

Regards

Can you post an image of the geometry? Is it a simple pipe with closed ends, or does it have some other detail.

This does not sound like a multi domain problem to me. Should be able to do it with a single domain with careful specification of initial conditions.
