Although it is been a while, it is my pleasure to announce my PhD solver helmholtz-x on discourse here, upon @dokken’s suggestion!
I spent my PhD on solving thermoacoustics helmholtz equation using FEniCSx and its components.
Please access the code on my GitHub repository and accompanying paper.
I hope you find it useful for your own FEniCS applications!
If you have any questions, please don’t hesitate to contact!
