Abstract: Embodiments are presented for topology graph optimization. A design geometry is represented as a graph. Engineering objectives and constraints are associated with a graph representation of a design geometry. The graph representation of the design geometry is iteratively refined for analysis using an optimization algorithm. The graph representation of the design geometry is evaluated according to constraints and objectives associated with the desired resulting design. The optimization results can be further refined by updating objectives and constraints. The optimization results may be machined directly.
