Enhancements to AVAST

Abstract

The development and incorporation of the latest enhancements to the AVAST code are described. The purpose of this work was to make the modelling of the physical environment more realistic, while ensuring that the code runs as efficiently as possible. To this end, several new features have been added. These include the implementation of a four-noded acoustic panel element and the development of an eigenvalue extraction technique suitable for equations generated by the boundary integral equation method. In addition, the option to use structural response data generated by the COUPLE program has been incorporated.
