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#

Output Parameter#

  • maxDof - the maximum dof

Note#

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

Developer Note#

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.
