GFS_IS_FLUID()

#define             GFS_IS_FLUID(cell)

Evaluates to TRUE if cell is entirely contained in the fluid, FALSE otherwise.

GFS_IS_MIXED()

#define             GFS_IS_MIXED(cell)

Evaluates to TRUE if cell is partially contained in the fluid, FALSE otherwise.

GFS_FACE_FRACTION()

#define             GFS_FACE_FRACTION(fa)

GfsSolidVector

typedef struct {
  gdouble s[FTT_NEIGHBORS];
  gdouble a, v, fv;
  FttCell * merged;
  FttVector cm, ca;
} GfsSolidVector;

Contains the surface and volume fractions of the cell not contained in the solid.

gfs_cell_fluid ()

void                gfs_cell_fluid                      (FttCell *cell);

Sets cell and all its descendants as full fluid cells.

gfs_cell_init_solid_fractions_from_children ()

void                gfs_cell_init_solid_fractions_from_children
                                                        (FttCell *cell);

Uses the values of the solid fractions of the children of cell to compute the values of its solid fractions.

This function fails if cell is a leaf of the cell tree.

gfs_cell_check_solid_fractions ()

gboolean            gfs_cell_check_solid_fractions      (FttCell *root);

Checks the consistency of the solid fractions of each cell of the cell tree relative to the neighboring solid fractions.

gfs_cell_traverse_mixed ()

void                gfs_cell_traverse_mixed             (FttCell *root,
                                                         FttTraverseType order,
                                                         FttTraverseFlags flags,
                                                         FttCellTraverseFunc func,
                                                         gpointer data);

Traverses a cell tree starting at the given root FttCell. Calls the given function for each mixed cell.
