Thank you for your response

Here is a result, all the boundary conditions is created by me. Except wall-part-vapor_chamber_fluid_v1.2-part-vapor_chamber_v1.3 and it's shadow

 

Here is a photo of wall-part-vapor_chamber_fluid_v1.2-part-vapor_chamber_v1.3:

Just one question here:

wall-part-vapor_chamber_fluid_v1.2-part-vapor_chamber_v1.3 is considered as interface boundary condition, right?
