What is topology optimization?
Topology optimization is a mathematical method used across many engineering mediums to optimize a structure or component’s layout to minimize its weight by removing excess material, reducing thermal stress or achieving other desired performance goals.
How does topology optimization work?
Topology optimization uses algorithms to find the best material distribution within a design space, considering constraints like stresses and thermal loads.
While traditional methods focus on compliance, ColdStream optimizes various objectives such as temperature minimization and variance reduction, and handles constraints like pressure loss.
ColdStream starts with an empty design space and builds up the structure, achieving high performance with minimal material use. This approach results in complex, efficient designs that often exceed the capabilities of traditional methods.
