[deal.II] affine representation

Hi, I am solving a linear system (say linear heat conduction) with many different materials (blockID) whose material properties are uncertain. My goal is to use a RB approach to build the ROM. However, while building the snapshots, for every new sample, I need to reassemble the system

[deal.II] L2 norm of distribution solution

Hi, I have a solution vector with locally owned and locally relevant dofs. I want to compute its L2-norm. Using the l2_norm() on it caused a Trilinos error (I was going to compute the squared of the L2 norm, then do an MPI Allreduce on the resulting values). So, I decided to code it "by hand"
