Hi,

I am simulating a bubble rising problem using Moving mesh method. I have a problem and I do appreciate your help. The problem is here that the bubble rises in water normally due to gravity, but the bubble radius decreases over time, which I think is not physical. I refined the mesh several times, but the problem did not disappeared. I think something should be done with the settings of moving mesh. By default the water tank and the bubble are deforming domain and no more settings. Does anyone know what the problem is?

Thank you Hamid

Hello, I would upload your model so people could look at the setup.
