DMAdaptationCriterion

Describes the test used to decide whether to coarsen or refine parts of the mesh

Synopsis

typedef enum {
  DM_ADAPTATION_NONE,
  DM_ADAPTATION_REFINE,
  DM_ADAPTATION_LABEL,
  DM_ADAPTATION_METRIC
} DMAdaptationCriterion;

Values

• DM_ADAPTATION_REFINE - uniformly refine a mesh, much like grid sequencing

• DM_ADAPTATION_LABEL - adapt the mesh based upon a label of the cells filled with DMAdaptFlag markers.

• DM_ADAPTATION_METRIC - try to mesh the manifold described by the input metric tensor uniformly. PETSc can also construct such a metric based upon an input primal or a gradient field.

• DM_ADAPTATION_NONE - do no adaptation
