NAFEMS: “Six Elements Per Wavelength” Rule in Acoustic Analysis

This webinar explores the commonly used “six elements per wavelength” guideline in acoustic simulations and its practical limitations. It aims to clarify mesh selection by discussing:

• Identification of relevant wavelengths in fluid and structural domains
• Influence of element type and order on accuracy
• Conditions where the rule applies or breaks down
• Examples illustrating mesh density and convergence behaviour
