dear everyone

I set 2d VOF model case, using patching function put a half circle shape droplet on the floor , hoping get a stactic droplet shape under the condition of the contact angle with 120 degree

In my case, I did not set any force any more, except the gravity.

and the droplet material is water, the enviroment is air, and the surface tension is 0.072, same as the example of the manual.

But the result of my case is quite weird, the bubble shape is keep change in a unreasonable way.

can anyone offer some advice?
