PetscDTNodeType#

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

Synopsis#

`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
