Hi,

I'm looking for an toy problem which leads to solving
a sparse but unstructured linear system.

As I need it for teaching students during their first
year, it should not be a partial differential equation
in 2d or 3d.
Bending a beam would be fine, but there I get a
structured matrix, which is not what I'm looking for.

Greetings, Uwe.

what about currents/ voltages in an electrical network (stationary case)
where you can connect nodes as you wish?
