The macros listed in Table 3.2.20- 3.2.23 can be used to return real face variables in SI units. They are identified by the F_ prefix. Note that these variables are available only in the pressure-based solver. In addition, quantities that are returned are available only if the corresponding physical model is active. For example, species mass fraction is available only if species transport has been enabled in the Species Model dialog box in ANSYS FLUENT. Definitions for these macros can be found in the referenced header files (e.g., mem.h).
Face Centroid (
F_CENTROID)
The macro listed in Table 3.2.20 can be used to obtain the real centroid of a face. F_CENTROID finds the coordinate position of the centroid of the face f and stores the coordinates in the x array. Note that the x array is always one-dimensional, but it can be x[2] or x[3] depending on whether you are using the 2D or 3D solver.
The ND_ND macro returns 2 or 3 in 2D and 3D cases, respectively, as defined in Section 3.4.2. Section 2.3.15 contains an example of F_CENTROID usage.
Face Area Vector (
F_AREA)
F_AREA can be used to return the real face area vector (or `face area normal') of a given face f in a face thread t. See Section 2.7.3 for an example UDF that utilizes F_AREA.
By convention in ANSYS FLUENT, boundary face area normals always point out of the domain. ANSYS FLUENT determines the direction of the face area normals for interior faces by applying the right hand rule to the nodes on a face, in order of increasing node number. This is shown in Figure 3.2.1.
ANSYS FLUENT assigns adjacent cells to an interior face ( c0 and c1) according to the following convention: the cell out of which a face area normal is pointing is designated as cell C0, while the cell in to which a face area normal is pointing is cell c1 (Figure 3.2.1). In other words, face area normals always point from cell c0 to cell c1.
Flow Variable Macros for Boundary Faces
The macros listed in Table 3.2.22 access flow variables at a boundary face.
Summer 2025 is shaping up to be a season defined by "meaningful minimalism and joyful colors". The frivolous dress order is not a mistake; it is a strategic response to the oppressive heat and the yearning for lightness.

I should structure this as a lifestyle/opinion article. The tone should be witty, relatable, and slightly humorous, targeting young women or fashion enthusiasts. I'll break down the keyword: "frivolous dress order" as the impulsive buy, "post its hot" as the regret or challenge after the weather turns hot. The article can explore the psychology of impulse shopping, the specific problem of ordering impractical clothes for hot weather, and offer solutions like styling tricks or cooling fabrics. I'll include a narrative hook, personal anecdotes, practical tips, and a conclusion that ties back to mindful consumption. I need to ensure the exact keyword appears naturally in the headline, introduction, and at least once in the body, maybe as a highlighted section. frivolous dress order post its hot

This refers to an absurd, overly strict, or highly publicized corporate dress code policy. In corporate law and HR history, "frivolous orders" usually refer to legal demands lacking any serious purpose. Applied to fashion, it represents the modern rebellion against unnecessary, outdated workplace attire rules.

Flow Variable Macros at Interior and Boundary Faces
The macros listed in Table 3.2.23 access flow variables at interior faces and boundary faces.
F_FLUX can be used to return the real scalar mass flow rate through a given face f in a face thread t. The sign of F_FLUX that is computed by the ANSYS FLUENT solver is positive if the flow direction is the same as the face area normal direction (as determined by F_AREA - see Section 3.2.4), and is negative if the flow direction and the face area normal directions are opposite. In other words, the flux is positive if the flow is out of the domain, and is negative if the flow is in to the domain.
Note that the sign of the flux that is computed by the solver is opposite to that which is reported in the ANSYS FLUENT GUI (e.g., the Flux Reports dialog box).
