Hi,

I would like to use a moving mesh inside a sphere. It is important to have two separated threads (one for gas and one for liquid).
So I defined the motion of a wall (inside the sphere) with DEFINE_CG_Motion.

But when the wall moves through the sphere the length of the moving wall is constant (picture attached). This way it won't work, because it should be a model of a tank.

Is it possible to move a wall through the sphere, so that I can work with two regions (devided by the wall)? Maybe with a variable length of the moving wall?

Thank you very much for your help!
