This CAREER project develops an adaptive space-time finite element
methodology that allows for accurate and efficient prediction of the
dynamic response of complex structural acoustic systems over a broad
range of scales and frequencies - including the mid-frequency range. The
methods employ finite element discretization of the time domain as well
as the usual discretization of the spatial domain. This novel approach to
the modeling of the temporal variables allows for the consistent use of
adaptive solution strategies for unstructured grids in both time and
space: a technique which significantly improves the efficiency and
reliability of the resulting computational algorithm over standard
methods. By orchestrating the distribution of mesh sizes and spectral
orders in space-time, a modeling technique is obtained which has
significant flexibility and scope. The educational plan enhances the
learning process for both undergraduate and graduate students through a
comprehensive array of innovative teaching activities and industrial
exchanges. Educational activities include development of a curriculum in
finite element analysis, setting up experimental, computational, and
multimedia laboratories for graduate and undergraduate teaching, use of
symbolic computing systems for innovative teaching and learning,
involving undergraduate students in collaborative research projects,
educational collaborations with industry, and outreach activities
including delivering short courses and workshops over the Internet via
video conferencing and the World Wide Web.
