KSPDMActive

Indicates if the DM attached to the KSP should be used to compute the operator, the right-hand side, or the initial guess

Synopsis

typedef enum {
  KSP_DMACTIVE_OPERATOR      = 1,
  KSP_DMACTIVE_RHS           = 2,
  KSP_DMACTIVE_INITIAL_GUESS = 4,
  KSP_DMACTIVE_ALL           = 1 + 2 + 4
} KSPDMActive;

Values

• KSP_DMACTIVE_OPERATOR - compute the operator

• KSP_DMACTIVE_RHS - compute the right-hand side

• KSP_DMACTIVE_INITIAL_GUESS - compute the initial guess

• KSP_DMACTIVE_ALL - compute all of them
