Hey Everybody,

i try to create a Matrix UEqn for the correction Loop.
The Equatin is:
U and k are vectors and T and Ra are scalars.

Is there a way to create a Matrix like
fvVectorMatrix UEqn
- Ra*T*k
but this doesnt work

Thanks for Help!

mprinkey will become famous soon enough
You need to use fvm::Sp(U) (or fvm::S for the linear source term, so something like:

fvVectorMatrix UEqn
fvm::Sp(U) - Ra*T*k

should work. Note that this is just a diagonal matrix.
