TSDGType

Selects the discrete-gradient flavor used by TSDISCGRAD when integrating gradient-system ODEs

Synopsis

#include <petscts.h> 
typedef enum {
  TS_DG_GONZALEZ,
  TS_DG_AVERAGE,
  TS_DG_NONE
} TSDGType;

Values

• TS_DG_GONZALEZ - Gonzalez’s mid-point-style discrete gradient

• TS_DG_AVERAGE - average vector field (AVF) discrete gradient

• TS_DG_NONE - do not apply a discrete gradient correction; the integrator falls back to a standard mid-point rule
