Acoustic-Structure Interaction and Air Flow in Violins

Application ID: 34861


These models are featured in the blog post Analyze Violin Tone and Volume with Multiphysics Modeling. One applies acoustic-structure interaction to study how the air mode resonance is affected by the coupled vibrations in the violin body. The other uses a potential flow approximation to find out how the air flow through the sound holes relates to their shape.

Both models were inspired by, and give results that are well in line with, this paper:
