Gerris structures

CellCube

typedef struct {
  GtsPoint p[8];
  GfsSegment s[12];
}

The vertices of the cube are stored in the GtsPoint array and the edges in the GfsSegment array.

CellFace

typedef struct {
  GtsPoint p[4];
  GfsSegment s[4];
}

The vertices of the face are stored in the GtsPoint array and the edges in the GfsSegment array.

CompatPar

typedef struct {
  GfsVariable * lhs;
  gboolean dirichlet;
}

The homogeneous version of the considered GfsVariable is stored in lhs.

DiffusionCoeff

typedef struct {
  GfsSourceDiffusion * d;
  gdouble lambda2[FTT_DIMENSION];
  gdouble dt;
  GfsVariable * rhoc, * metric;
  GfsFunction * alpha;
  GfsDomain * domain;
}
