Open Source Computational Acoustics with FEniCSx - Part 2

In this second lesson Antonio Baiano Svizzero completes the previous script adding an acoustic impedance (Robin) boundary condition. First it is supposed to be constant, while later a csv impedance spectrum is imported.
The differences between the previous case and this one are shown both in terms of sound pressure spectrum on one microphone point and sound pressure field.

Thanks a lot for providing such a complete and clear video about the subject ! I am really looking foward to the next one. Do you plan to make one about perfectly matched layer and absorbing boundary conditions ? However, I am currently encountering a problem with Gmsh, I installed it with pip but when I try to launch it via prompt or python, I have an error stating that the module GLIBC_2.23 is missing. Have you already encountered such issue ?

Thank you for the nice comment. Very soon we''ll post a video about monopoles and PMLs! Stay tuned. Sorry, gmsh has always been working smoothly here.

Well done, thank you for linking to this video - I'd love to watch the next one. I don't know if you know, in np.loadtxt there is an "unpack" option - example: f, rel, im = np.loadtxt("file", unpack=True). I like the "unpack" option because it makes my job easier. Thanks again for the video and the link in the email reply.

Thank you very much! Do you have any suggestion on the next topic?
