Sound propagation in a 3D parallepipedic cavity

General

Hello guys,

As always, I want to share my results about the acoustic simulation that I am performing using dolfinx. This time I tried to be as close as possible to “real life” simulation: starting from the CAD (FreeCAD), I meshed the geometry with gmsh, run the simulation with FEniCSx and postprocessed the results with Paraview.
Such a workflow can be applied to more complex geometries quite easily.

Check the related article here:

This is one of the results:

I hope to find someone else interested in acoustic simulation.

Hi @bay_swiss,
This is really cool! Thanks for sharing! May I ask what filters did you use to generate the animation?

Hi @Kei_Yamamoto ,
I used a Programmable Filter, in which you can manipulate the data however you want!
