A procedure for structural shape optimization using nonlinear structural analysis commercial software ABAQUS is described. Domain elements are used to define the regions of the shape change in the structure, while basis vectors are employed to specify allowable shape changes in the structure. Theoretical background behind both domain elements and basis vectors are discussed. Shape optimization is performed using the commercially available, general-purpose software package VisualDOC. A general procedure for coupling ABAQUS and VisualDOC is discussed in detail. The proposed methodology is demonstrated using two example problems.
