There was a problem hiding this comment.
Some first comments, mostly in line with #660. Somehow, I could not run the Nutils solver on my system. I can also try in a newer system, but maybe you know what else I could try.
Sorry, something went wrong.

This PR adds a new Partitioned Pipe Multiscale tutorial demonstrating steady 1D–3D coupling with preCICE for incompressible pipe flow.
The tutorial is particularly relevant as it provides a clear and controlled benchmark for testing and illustrating the axial geometric multiscale mapping in a steady-state setting. It focuses on a laminar Poiseuille flow configuration, enabling direct comparison of axial pressure distributions and velocity profiles across the coupling interface.
It includes 1D–3D and 3D–1D configurations, as well as 1D–1D and 3D–3D variants for validation and comparison.
