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?”

DMDA knows about components so that MatStencil has a .c slot for indices. Is that what you mean?

Thanks,

What most experimenters take for granted before they begin their experiments is infinitely more interesting than any results to which their experiments lead.
