Default Shock Tube problem

Hello, I am trying to model flow in a shock tube using fluent. I was able to initialize the flow by imposing initial conditions as such: at t=0, P driver= P4 (patching) with helium, Pdriven= P1 (default init)with Ar, The problem is that the results of pressure and Mach number do not agree with the analytical inviscid solution. For some odd reason, I see a sustained high mach near the diaphragm throughout the entire simulation, as a result, there are two incident shocks generated. Any one had the same problem? What is the best way to initialize the problem. Thanks

Mouna
