How to set boundary to a floating potential

Hello,

I am wondering how to set an external boundary to a floating potential?

Suppose I have a cube and desire different boundary conditions for each face. X- and Y- faces reflective, one Z- face with a floating potential and the other Z- face with 0V potential to simulate neutral plasma. How can I do this?

Thanks,
Tyler

Hello,
the Z face must be a material surface in this case

hi, have you been able to create an external boundary ? I am facing some problems with defining the external boundary for a spacecraft geometry

Hi Shagun,

Yes I have gotten it to work. What kind of problems are you having? I may be able to help
