Hi everyone 

When I use Fluent Polyflow, I face two significant limitations:

• I would like to apply a constant pressure boundary condition directly on a free surface, similar to what is possible in Polydata, without using VOF or defining a second phase.
  It seems this is not directly available.
• I also cannot find any option to apply surface tension on a free surface unless a second phase (VOF) is introduced.

My goal is to model a free surface where I can impose both:

• constant pressure, and
• surface tension

without defining a second fluid phase.

Could you please help in the matter that whether this is possible in Fluent Polyflow? And if so, provide guidance or an example or anything helpful?
