[petsc-users] jacobians for multicomponent problems

Suppose I have a problem for which the field variable has multiple components, in this case real and imaginary parts, and I have created a DM with two degrees of freedom.  When assembling a Jacobian associated with a nonlinear problem on this data, is there any data management accounting for the different components that makes this “easier?”
