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#

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
