Hello,
I need to do some post-processing on computed solution data (say
Vector Solution(dof_handler.n_dofs()) is the solution vector). For
post-processing field (say Vector Curvature(triangulation.n_dofs())
is the scalar field to be computed) I decided to have one entry per cell.
Once I calcula
Hello,
Thank you for your suggestions.
In essence, what happens here is that your solver has just diverged.

Hi,
I am a new deal.II user.
I'm solving a 2D problem on quadrilateral cartesian mesh using FE_Q(1)
elements.
I would like to compute the gradient of the bilinear solution, known to
belong to the FE_Nedelec(0) space: how can I manage to do it?
In particular I'm only interested in computing the

Thank you all for your responses. As suggested, I'll send a message to the
Spack forum and/or open an issue on their GitHub site. In the meantime,
I'll continue debugging the manual PETSc installation to see if I can get
that to work. I think the filesystem I'm tryin

I think the best place to report such problems
is https://github.com/LLNL/spack/issues
Looking at your error, i think it happens within your cluster, as it's
