hi, i am modelling a rectangular enclosure in 2D in gambit. There is liquid inside this enclosure. I have defined the 4 edges as "walls" how do i define the liquid in the enclosure? Do i create a face first?

In gambit you neednot do anything (other than selecting 2-D export)

In fluent a default interior will be automatically created whose material propoerties you can change as per requirement.

ok thanks... but do i still need to create a face on the area and mesh it rite?
