This is definitely doable.

Hello all,
I'm attempting to set material ID based on x-location. I'd like to create
std::unordered_map between x-locations of cell centers and material id, and
then refer to that map to quickly set material_id later.

Hi Praveen,
Thanks for the helpful answer. I'm new to Visit; would you mind specifying
how to view the subset of data (e.g., faces with boundary ID 0)?
Best,

Hi there,
I'm currently trying to pack my cell operations into one of the matrix-free
loop functions.
In my first version, I implemented the loops manually by using (sorry for
the odd formatting):
```
local_apply_cell(*matrix_free,

Perfect, thank you very much. Unfortunately, the make_sparsity_pattern()
method I was looking for is displayed after make_flux_sparsity_pattern() in
my online docu., so I overlooked them, sorry for that.
That's a good starting point to add a method for each level and I need some
flux sparsity f
