face_t Derived Type

type, public :: face_t

Mesh face data structure. Faces are the primary entities for flux calculation. Each face is associated with an 'owner' and potentially a 'neighbor' cell.

      integer :: periodic_face = 0     !< ID of the matching face on the opposite periodic boundary.
      integer :: periodic_neighbor = 0 !< ID of the neighbor cell accessed through periodic matching.
      real(rk) :: normal(3) = zero     !< Unit normal vector pointing outward from the owner cell.
      real(rk) :: area = zero          !< Surface area of the face [m^2].
      real(rk) :: center(3) = zero     !< Coordinates (x, y, z) of the face centroid.
