The use of fixed finite element meshes to conduct transient analyses that involve ever changing boundary shapes as well as boundary specifications is the subject of this research. The first efforts in this direction led to the development of the pseudo-concentration method. Current research centers on ways of specifying boundary conditions at material interfaces with a greater degree of accuracy and with greater computational efficiency.

Status: Current project is completed. Additional research is needed to extend interface techniques to three dimensional problems and to couple them with the pseudo-concentration method.
