Hello Everyone,

I have 2D Axisymmetric VOF model. The model has air-water zones in the domain. Please look at the image of the model that I attached with this message. A droplet is on top of thin liquid film at time step 0. What I like to see is how this droplet moves with the effect of gravity and surface tension for different time steps. However, as you can see in the image that shape of droplet and liquid film does not change after some time step and remains like that.

What might be the reason for this? I used "Adapt-Region" in order to create a droplet and thin liquid film for specific dimension.

Further questions: How can I assign movement to a droplet(s) rather than using only gravity? For instance: 10 m/s in -y direction. Do I have to use "Dynamic Mesh" method or is there any other options or methods to give a movement to droplet?

Thanks.
