PetscDTNodeType#
A description of strategies for generating nodes (both quadrature nodes and nodes for Lagrange polynomials)
Synopsis#
typedef enum {
PETSCDTNODES_DEFAULT = -1,
PETSCDTNODES_GAUSSJACOBI = 0,
PETSCDTNODES_EQUISPACED = 1,
PETSCDTNODES_TANHSINH = 2
} PetscDTNodeType;
Values#
PETSCDTNODES_DEFAULT- Nodes chosen by PETScPETSCDTNODES_GAUSSJACOBI- Nodes at either Gauss-Jacobi or Gauss-Lobatto-Jacobi quadrature pointsPETSCDTNODES_EQUISPACED- Nodes equispaced either including the endpoints or excluding themPETSCDTNODES_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.
