| dm | - The DMPlex object | |
| dim | - The spatial dimension of the problem | |
| numFields | - The number of fields in the problem | |
| numComp | - An array of size numFields that holds the number of components for each field | |
| numDof | - An array of size numFields*(dim+1) which holds the number of dof for each field on a mesh piece of dimension d | |
| numBC | - The number of boundary conditions | |
| bcField | - An array of size numBC giving the field number for each boundry condition | |
| bcComps | - [Optional] An array of size numBC giving an IS holding the field components to which each boundary condition applies | |
| bcPoints | - An array of size numBC giving an IS holding the Plex points to which each boundary condition applies | |
| perm | - Optional permutation of the chart, or NULL |
Notes: numDof[f*(dim+1)+d] gives the number of dof for field f on sieve points of dimension d. For instance, numDof[1] is the number of dof for field 0 on each edge.
The chart permutation is the same one set using PetscSectionSetPermutation()
