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;
`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.
