Automotive cabin: application of Acoustic Modal Analysis
Introduction After a lot of mathematics and python coding, you could wonder if there are limitation to the capabilities of what has been developed in the previous articles. Starting from…
Modal Superposition in Acoustic Cavities
Introduction The last time a modal analysis has been performed on a parallepipedic cavity and all the modal shapes have been computed up to the desired frequency. The coincidence between…
Introduction to Acoustic Modal Analysis
Introduction In previous articles, starting from the Helmholtz equation, the corresponding weak form and the related algebraic system of equation have been shown, then the system has been directly solved. Such an…
Sound propagation in 3D cavities
Introduction Hello everyone! In the last articles the way a FEniCSx code has to be written in order to perform an acoustic simulation has been explored. The 2D case was intended to be…
Acoustic boundary conditions: implementation in FEniCSx
IntroductionIn the last (and first) article we talked about the Helmholtz equation and its implementation in FEniCSx for the solution of a point source propagating in a square 2D room.…
2D Helmholtz equation with FEniCSx: point source in a square room
IntroductionThis is the first article of a long series. My goal is to explain the process of performing a full aero-vibro-acoustic simulation on a real system, of industrial interest. This…
