PetscDTNodeType#

A description of strategies for generating nodes (both quadrature nodes and nodes for Lagrange polynomials)

Synopsis#

typedef enum {
  PETSCDTNODES_DEFAULT = -1,
  PETSCDTNODES_GAUSSJACOBI,
  PETSCDTNODES_EQUISPACED,
  PETSCDTNODES_TANHSINH
} PetscDTNodeType;

Values#

PETSCDTNODES_DEFAULT - Nodes chosen by PETSc
PETSCDTNODES_GAUSSJACOBI - Nodes at either Gauss-Jacobi or Gauss-Lobatto-Jacobi quadrature points
PETSCDTNODES_EQUISPACED - Nodes equispaced either including the endpoints or excluding them
PETSCDTNODES_TANHSINH - Nodes at Tanh-Sinh quadrature points

Note#

A PetscDTNodeType can be paired with a PetscBool to indicate whether the nodes include endpoints or not, and in the case of PETSCDT_GAUSSJACOBI with exponents for the weight function.

Level#

intermediate
