3.1. Create design hints
- Topology Optimization: OptiStruct uses topology optimization to generate recommendations for creative design ideas. OptiStruct generates an optimal design suggestion based on user-defined design space, performance goals, and production constraints. Topology optimization can be applied to 1D, 2D, and 3D design types.
- Tendon optimization: For thin-walled structures, tendon structures are often used for reinforcement. With a given size, OptiStruct's ribbed optimization technology generates innovative design suggestions with optimal pattern and rib position for reinforcement to meet certain performance requirements. Typical applications include the hardness rating table and the high specific frequency.
- Free-size optimization: Free-size optimization is widely applied to finding, distributing the optimum thickness in machined metal structures and determining optimal layer shapes in composites . Element thickness per material layer is a design variable in free dimensional optimization.
3.2. Optimized for design refinement
- Dimension optimization: The optimal model parameters such as material properties, cross-section size can be determined through dimensional optimization.
- Shape optimization: Shape optimization is done to refine an existing design through user defined shape variations. Morphing morphing transformations - Altair HyperMorph - are available in Altair HyperMesh.
- Free shape optimization: OptiStruct's exclusive solution for parametric geometry optimization, automatically generates shape transformations and determines the optimal contour shape based on design requirements. This frees the user from the task of defining shape distortions and allows for flexible design improvement. Free-form optimization is very effective in reducing highly concentrated stress.
3.3. Design and optimization of layers of composite materials
A unique 3-phase process has been implemented in OptiStruct to assist with the design and optimization of the composite material layer. The process is based on a natural modeling method that is easy to use. This also facilitates the incorporation of various manufacturing constraints, such as layering, that is specific to composite design. Applying this process yields optimal layer geometry (stage 1), optimal number of layers (stage 2), and optimal layering sequence (stage 3).
3.4. Design and optimize network structures in 3D printing
The network structure offers many desirable properties such as lightweight and durable thermal properties. They are also highly anticipated in biomedical implants due to their porous nature and their ability to facilitate the integration of cartilage tissue structures. OptiStruct has a unique solution for designing those complex structures based on topology optimization. Large-scale dimensional optimization studies can then be run in conjunction with detailed targets such as stress, axial stability, displacement, and frequency.
