:orphan: # PetscQuadratureExpandComposite Return a quadrature over the composite element, which has the original quadrature in each subelement ## Synopsis ``` #include "petscdt.h" PetscErrorCode PetscQuadratureExpandComposite(PetscQuadrature q, PetscInt numSubelements, const PetscReal v0[], const PetscReal jac[], PetscQuadrature *qref) ``` Not Collective; No Fortran Support ## Input Parameters - ***q -*** The original `PetscQuadrature` - ***numSubelements -*** The number of subelements the original element is divided into - ***v0 -*** An array of the initial points for each subelement - ***jac -*** An array of the Jacobian mappings from the reference to each subelement ## Output Parameter - ***dim -*** The dimension ## Note Together v0 and jac define an affine mapping from the original reference element to each subelement ## See Also `PetscQuadrature`, `PetscFECreate()`, `PetscSpaceGetDimension()`, `PetscDualSpaceGetDimension()` ## Level intermediate ## Location src/dm/dt/interface/dt.c --- [Edit on GitLab](https://gitlab.com/petsc/petsc/-/edit/release/src/dm/dt/interface/dt.c) [Index of all DT routines](index.md) [Table of Contents for all manual pages](/manualpages/index.md) [Index of all manual pages](/manualpages/singleindex.md)
