Dear All,
I ve noticed that OF supports Implicit/Explicit source for a product of scalar by vector U, like:

fvm::SuSp(scalarfield, U)

But what if I need an implicit source for each component of U, like:

Sp = volVectorField
fvm::SuSp(Sp, U),

where in the x component of moment equation I would have:

fvm::SuSp(Sp.component(0), U.component(0))

and so on...?

(The components of Sp are independent...)

Then you're in trouble: the diagonal for a vector quantity in the current version is a vector only next to a boundary. Therefore, internally you can only add a scalar SuSp contribution.

My block matrix rewrite fixes this (along with a number of other block-solution related things) but this is not ready for public consumption just yet.
