[Trilinos-Users] EpetraExt::ModelEvaluator, dF/dp w.r.t. to which parameter?

[Nico Schlömer]

Hi all,

I have an EpetraExt::ModelEvaluator with a number of different model
parameters, all contained in 1 parameter vector (as returned by
get_p_init()). When calculating dF/dp, though, the resulting
multivector

  const Teuchos::RCP<Epetra_MultiVector> dfdp_out =
      outArgs.get_DfDp(0).getMultiVector();

will always contain 1 vector. -- Apparently, the application wants me
to return dF/dp w.r.t. to one of them. Any idea how to tell which one
it is?

Cheers,
Nico
