I have question of compressible flow.

I have closed tube where left and right and upper boundary conditions is of wall type and then since the problem is axisymmetric we have axis boundary condition in the bottom. Now I have discontinuity at about half of the length and on the left side of discontinuity we have pressure of 1 bar and right side of the discontinutiy we have pressure of 2 bar. My question is how can set two different initial condition on the left and right side of discontinuity.

Use "patching", look for more help in the UG.
