String Method Boundary Element Method (BEM) analysis involves a computational approach for simulating wave propagation phenomena. It is particularly suited to modeling acoustic radiation and scattering, especially in complex or unbounded domains. This method discretizes surfaces using elements and applies specialized Green’s functions to determine the acoustic pressure and velocity at these elements. For example, analyzing the noise emitted from a vibrating structure submerged in water would employ this type of analysis.
This computational model offers significant advantages in acoustic analysis due to its ability to handle infinite boundaries accurately and efficiently. By reducing the problem dimensionality to surface computations, it often requires fewer resources than full domain methods like Finite Element Analysis (FEA). Historically, developments in BEM have allowed for progressively complex simulations, contributing to advancements in areas such as noise control engineering, underwater acoustics, and medical ultrasound.
