# PetscFVFaceGeom

Data structure (C struct) for storing information about face geometry for a finite volume method.

## Synopsis

    typedef struct {
      PetscReal   normal[3];   /* Area-scaled normals */
      PetscReal   centroid[3]; /* Location of centroid (quadrature point) */
      PetscScalar grad[2][3];  /* Face contribution to gradient in left and right cell */
    } PetscFVFaceGeom;

## Note

The components are

      PetscReal   normal[3]   - Area-scaled normals
      PetscReal   centroid[3] - Location of centroid (quadrature point)
      PetscScalar grad[2][3]  - Face contribution to gradient in left and right cell
