PetscSectionGetMaxDof#

Return the maximum number of degrees of freedom on any point in the chart

Synopsis#

#include "petscsection.h"   
PetscErrorCode PetscSectionGetMaxDof(PetscSection s, PetscInt *maxDof)

Not Collective

Input Parameters#

  • s - the PetscSection

Output Parameter#

  • maxDof - the maximum dof

Notes#

The returned number is up-to-date without need for PetscSectionSetUp().

Developer Notes#

The returned number is calculated lazily and stashed. A call to PetscSectionInvalidateMaxDof_Internal() invalidates the stashed value. PetscSectionInvalidateMaxDof_Internal() is called in PetscSectionSetDof(), PetscSectionAddDof() and PetscSectionReset(). It should also be called every time atlasDof is modified directly.
