The finite element model of underwater structure with shafting is built by ANSYS. The characteristics of structural acoustic radiation are investigated by the direct boundary element method.
The fundamental theories of acoustic finite element method and finite volume method, as well as the related software SYSNOISE and FLUENT are introduced.
