Detailed Description

Simple ETA test to compare ETA to ADRAssembly in a 2D space with a 2D solution.

Author: L. Pasquale luca..nosp@m.pasq.nosp@m.uale@.nosp@m.mail.nosp@m..poli.nosp@m.mi.i.nosp@m.t

This test computes the matrix associated to the advection-diffusion-reaction linear operator:
$Lu=-\alpha \delta u + \beta \cdot \nabla u +\gamma u$
with $\alpha=1$ , $\beta=\left(\begin{array}{c}1\\0\end{array}\right)$ , $\gamma=2$ and $u$ a 2D field
The domain is the square (-1,1)x(-1,1).
The matrix is first assembled using the class ADRAssembler and then the ExpressionAssembly::integrate function of the ETA module.
if the two matrices are assembled correctly, they should be almost exactly the same.
