What is topology optimization?
Topology optimization is an algorithmic process that reveals the most efficient design based on a set of constraints or characteristics, often by removing material from the design. It concerns the number of connected components/boundaries belonging to the domain. Topological optimization techniques help users work around the limitations of pure shape optimization.
Improve design processes with topology optimization
Topology optimization usually occurs near the end of the design process, typically when you run into weight emergency or need to reduce material costs. It is a mathematical method that uses simulation technology to predict performance without the need to interpret simulation results. Topology optimization technology automatically makes the changes required to improve the design.
How topology optimization is used
Use topology optimization algorithms to develop a variety of complex engineering and design solutions.
-
LIGHT-WEIGHTING
Improve strength-to-weight ratios by removing excess material that is not necessary for the design’s performance requirements.
-
SHAPE OPTIMIZATION
Shape optimization technology helps inform certain geometry decisions to specific constraints such as manufacturing methods.
-
STRUCTURAL COMPLIANCE
Calculate the physical response of a given shape, depending on the forces the shape is subjected to.
-
MULTIPHYSICS DESIGNS
Incorporate multiple types of physical phenomena such as fluid-structure interaction, thermal transfer, and stress loads to calculate optimal design.
The history of topology optimization
BIOMEDICAL ORIGINS
Early uses of topology optimization
Topology optimization was first used in the biomedical field for modeling implants to match the human skeletal structure. It then became widespread in aerospace. It is now used across advanced manufacturing industries.
