    Analyst Oriented Topology Optimization

    Analyst oriented topology optimization • Tool used by analysts • Operate on FE geometry • Nastran based optimization allowing to use all traditional Nastran

    elements (beams, solids, bars…) • Optimize for static loads, mode frequencies, dynamic loads, buckling

    loads …. • Define where Lattice structures can be used • Returns new smooth FE model with optimal configuration – validate the

    design • Returns new smooth CAD geometry with optimal configuration
