Minor correction

[pitipatw]

Summary

A short summary of the changes in this PR.

Highlights:

1. the argument in visualize does not have "u" (in u = solver.u , so it could not show the Makie figure.
2. I recheck with the VDO by Yijiang https://www.youtube.com/watch?v=sBqdkxPXluU and corrected them as in the clip, and now it works fine.

Minor changes:

1. change "; u= solver.u"
2. to "solver.u"

Thanks for the PR @pitipatw! We used to comment out the visualization lines because getting visualization code to run on GitHub actions was a pain. Can you please comment the lines out again after the correction you mentioned?

Sure! I will do that
