PetscDualSpaceGetSymmetries

Returns a description of the symmetries of this basis

Synopsis

#include "petscfe.h" 
PetscErrorCode PetscDualSpaceGetSymmetries(PetscDualSpace sp, const PetscInt ****perms, const PetscScalar ****flips)

Not Collective

Input Parameter

• sp - the PetscDualSpace object

Output Parameters

• perms - Permutations of the interior degrees of freedom, parameterized by the point orientation

• flips - Sign reversal of the interior degrees of freedom, parameterized by the point orientation

Note

The permutation and flip arrays are organized in the following way

  perms[p][ornt][dof # on point] = new local dof #
  flips[p][ornt][dof # on point] = reversal or not
