Input Parameters

dm - The DM, with a PetscDS that matches the problem being constrained
time - The time
locU - A local vector with the input solution values
field - The field to constrain
Nc - The number of constrained field components, or 0 for all components
comps - An array of constrained component numbers, or NULL for all components
label - The DMLabel defining constrained points
numids - The number of DMLabel ids for constrained points
ids - An array of ids for constrained points
func - A pointwise function giving boundary values
ctx - An optional user context for bcFunc

Output Parameter
