DMFieldContinuity#

Indicates the smallest mesh entity across which a DMField is continuous; equivalently, the largest entity at which the field may be discontinuous

Synopsis#

typedef enum {
  DMFIELD_VERTEX,
  DMFIELD_EDGE,
  DMFIELD_FACET,
  DMFIELD_CELL
} DMFieldContinuity;

Values#

DMFIELD_VERTEX - continuous across vertices (i.e., everywhere on the mesh; standard \(H^1\) finite elements)
DMFIELD_EDGE - continuous across edges, but may jump at vertices
DMFIELD_FACET - continuous across facets (faces in 3D, edges in 2D); may jump at lower-dimensional points
DMFIELD_CELL - field is defined per cell, with no continuity between adjacent cells (cell-centered finite volume)
