In the previous tutorial, we saw how to use the ETA framework with block structured matrices. This tutorial aims at investigating that more in detail.

In particular, 4 different strategies are proposed for the assembly of the Stokes matrix. The first one is the most simple strategy, but not the most efficient one. Two intermediate strategies are developed to show the influence of the different points. The last strategy represents the most efficient way of assembling the matrix.

In practice, only the first (simplest) and last (fastest) strategy should be considered since intermediate strategies have no advantages.
