Hi, I am a new user and I want to find out whether I can use deal.ii to 
solve a 2D problem where there are two unknowns; a scalar function of x,y 
and a scalar function of only x. I would like to initialize these as a 
vector and my test functions will have the same structure. 

Is it possible to declare this using FESystem and FE_Q?


I want to use a very simple mesh

GridGenerator::hyper_rectangle (triangulation, 

Point<2>(0,-0.05),

Point<2>(1,0.05)); 


and I thought 

fe (FE_Q<dim>(1), 1, 

FE_Q<dim-1, dim>(1), 1), 


may work but I am not sure whether I understood dim and spacedim correctly. 
Can this be done with the same triangulation for both unknowns?


I hope my question makes some sense and thanks in advance for any help.

Aycil.
