Degassing
 

Hi,

I want to simulate the forming of a glass bottle

I would like to know if it possible use a degassing option for a multiphase VOF model (air and glass) to allow air to escape from the mold but not the glass?
In positive case how I can activate this option?
What kind of VOF model? Is enough a homogeneous VOF model?

Thanks

If you want the phases to separate, i.e. different velocities at the same location, the model must be in-homogeneous.

Homogenous multiphase model --> shared field

So in a dishomogeneous case is possible the degassification condition?
How I can active it?

You have to check the documentation in detail. Specifically the outlet boundary condition for multiphase flow models.

From the documentation

In Pre, just define an outlet, there select the option 'Degassing Condition'.
