PetscSectionSetFieldDof#

Sets the number of degrees of freedom associated with a field on a given point.

Synopsis#

#include "petscsection.h"   
PetscErrorCode PetscSectionSetFieldDof(PetscSection s, PetscInt point, PetscInt field, PetscInt numDof)

Not Collective

Input Parameters#

  • s - the PetscSection

  • point - the point

  • field - the field

  • numDof - the number of dof, these values may be negative -(dof+1) to indicate they are off process

Note#

When setting the number of dof for a field at a point one must also ensure the count of the total number of dof at the point (summed over the fields and the unnamed default field) is correct by also calling PetscSectionAddDof() or PetscSectionSetDof()

This is equivalent to

     PetscSection fs;
     PetscSectionGetField(s,field,&fs)
     PetscSectionSetDof(fs,numDof)
