Teach functions/methods before loops, etc

1

Reported by @S-Stephen This would allow solutions be encapsulated in functions with prescribed names and interfaces.

Some students struggled in 2016 with the algorithmic complexity analysis. Expand material, either in the notebook or create some supplementary material.

Support mixed topology meshes

Support mixed topology (different cell) meshes. See https://github.com/FEniCS/dolfinx/projects/8

Support the VTK HDF5 IO format

1

VTK now has an HDF5 format for unstructured grids - https://kitware.github.io/vtk-examples/site/VTKFileFormats/#unstructured-grid. This format exploits more VTKs features than XDMF, and the future of XMDF is uncertain. It would be helpful...

Add matrix-free solver demos

It would be helpful to add a matrix-free solver demo. Problem should include boundary conditions. - [x] #1959 - [ ] Python version

Remove `Function::compute_point_values`

2

This function is slow and no longer required now that we have improved interpolation support. Remaining use is the in the IO code. Was removed from the Python interface in...

Some assembly-related functions are still missing to fully support assembly into a `la::MatrixCSR`, e.g. managing boundary conditions.

All MPI returned error codes should be checked.

A long standing issue is the 'magic' behind the scenes if interpolation to another space (usually P1) before output to a file. This is not sufficiently explicit, can be unexpectedly...
