change of volume inside pipe

Hello, First I would like to describe what i am doing. Description: There is a pipe closed at bottom and open at top(similar to test tube) with dimensions 0.126 m diameter and 0.5 m height. Inside the pipe there is concrete filled upto 0.124m dia and rest at the internal walls filled with lubricating layer(paste). Now side walls are moved down with a velocity of 0.6679m/s downwards. No dynamic mesh used. It is a static case. Now my problem is, I believe i have implemented everything fine in openFOAM and simulation ran succesfully. After some some i found the amount of lubricant which was initialised at walls is increasing in quantity and occupying entire cylinder. Concrete is not found. Don't know why ? I couldn't attach any case files here. For sharing those Im happy.

Hi ashok, Is it possible for you to send the case directory.

Hi Ashok, Can you mentiion the solver which you used for the simulation. Orelse I want you to try the simulation for Water-Air case by defining the surface tension sigma, which you defined as "0" before, to see the changes in the result. and we can think about Concrete-Air case. Regards, Sathish
