hello every one.
i want to make a 1D and two-phase (water-gas) testCase of shockwave but the interface is not deleted so water and gas does not mix and they stay still untile the end.
my solver : (compressibleInterFoam)


the properties for water and gas are as follows :


for gas :



adiabatic coefficient :1.4
wan der waals coefficient : 0
surface tension : 0.0725
ambient Temperature : 293.15 K
mu : 0

R = 287



for water :
surrounding Pressure : 101315 pa
rho = 998.206

gamma = 7.15

tait Pressure = 3046e5
mu= 0


the boundary condition of the velocity in the walls is : noSlip


at the end, my testCase has been uploaded. please help me to solve the problem thats mean : remove the interFace and mix the water with gas to get the correct pressure diagram. thanks
