Topology optimization refers to software program that takes advantage of the layout freedoms presented by means of additive production. It is a generative technique, so multiple design configurations are created for experimental testing with out introduced layout paintings. Plus, the diploma of physical checking out to gain an most suitable layout is reduced or removed by means of pushing generation to the software side.
One of the primary topology optimization applications was solidThinking from Altair. With Solidthinking, a designer would outline load facts and the software would use a mathematical method to generate a layout primarily based on that records. The software program indicated wherein non-vital cloth could be removed from the layout.

In general, topology optimization programs allow designers to create a design this is robust, lightweight, and minimizes cloth usage. Often, the end result is an organic shape, like something one might locate in nature. Because of these natural shapes, the first-class manufacturing tool is an additive manufacturing machine to build the design.

How topology optimization works:

–The first step is to outline the “design space” that represents the maximum volume a element can occupy. In this brake pedal instance, the design space is represented in orange.

–Then the hundreds described via the fashion designer are carried out and analyzed to provide several part design options. In this case, the brake pedal is supported at the give up, that could pivot. (In this situation, the end result looks like an natural truss shape.) 

An instance from General Electric is an engine bracket where the software program removed eighty four% of its weight the use of topology optimization. This component went on to be 3-D printed out of titanium the usage of selective laser sintering. The lower weight of the bracket became expected to shop the airline industry $31 million bucks thru electricity efficiency from simply one small part.

–The topology optimization application provides a end result that meets the described standards for a designer.

One of the important thing blessings of topology optimization is its capability to cut extra weight out of a design. Thus, the aerospace and car industries frequently use this software throughout layout.

Today, many CAD applications include a topology optimization module. Companies that provide topology optimization software program consist of Altair with solidThinking Inspire, Ansys, Autodesk Fusion 360, Dassault Systèmes, PTC, and Siemens amongst others.

In the Siemens supplying as an example, engineers and architects can combination topology optimization with conventional CAD facts.
Generative design is a variant of topology optimization software program. The predominant distinction is that it “generates” several design alternatives based totally on enter constraints together with material, feature, weight, and fee.

Generative layout is a computational layout technique that synthesizes parameters and objective dreams into an iterative set of rules to generate premiere structures.

An item’s optimized form is generated by using first defining forces exerted at the item, simply as in topology optimization. Design goals and pointers are then dictated before allowing the software the processing time to alliteratively  arrive at an “most desirable” answer. During each generation, a structural evaluation is computed, and those areas so that it will revel in less than a threshold stress or deflection are eliminated. This method repeats until one or greater designs are supplied to the clothier for final evaluation.
