Abstract

A structural shape optimization capability has been added to the MSC/NASTRAN finite element program. The grid locations in the finite element model are changed using a reduced basis method. The base shape vectors, required for the design model, could be generated either using a mesh generator or a static finite element analysis. Recognizing that shape optimization technology is making steady progress, the program structure is designed to be flexible and modular to include additional capabilities in future versions.
