摘要：

A high-order finite element infrastructure is described for the numerical solution of the vibratory response of fluid-structure systems in the mid-frequency range. Underlying variational forms along with the use of an unstructured, topology-based, variable-degree, polymorphic finite element discretization scheme is described. Accurate numerical solutions to practical problems, including rigid and elastic acoustic scattering and interior acoustics, are presented to demonstrate the accuracy and flexibility of the infrastructure.
