Input Parameters#

dm - DM to associate callback with
func - local boundary value evaluation
ctx - optional context for local boundary value evaluation

Calling sequence of `func`#

dm - the DM context
X - ghosted solution vector, appropriate locations (such as essential boundary condition nodes) should be filled
