You can do that by stopping the simulation after 70 timesteps and then changing the BC from Pressure Inlet to wall, and change all the BC you want to. Fluent will preserve the result from the previous timesteps, and you can use them. Regards

Am simulating compressed air inside a cylinder with piston the air starts to hit the wall of cylinder directly after 30 40 time steps and does not flow in the whole cylinder or act on it
