Simulation software could aid implant design ideas

Simulation software could aid implant design ideas

MSC Software Corporation (MSC), a computer-aided engineering (CAE) simulation software provider, has released MSC Apex Generative Design 2020, a tool that enables engineers to explore new approaches and optimise any part of their design in a single step to develop innovative products.

MSC Apex Generative Design aims to address product development pressures to meet shrinking budgets and rapid time-to-market by generating lightweight and smoothed preliminary component concepts based on the engineering goals.

It aims to do away with the iterative process of eliminating unsuitable candidates, freeing up the engineer’s time so they can use their expertise to explore the design space and find more optimal and novel solutions by fine tuning pre-vetted, manufacturing-ready designs.

With MSC Apex Generative Design:

  • A surgeon can create a smarter, latticed implant design that’s pre-validated for additive manufacturing and the same weight as the bone it replaced, improving biocompatibility to encourage muscle attachment and patient comfort.
  • Manufacturers can fully exploit the capabilities of additive manufacturing and optimise their designs to enable first-time-right part production for entirely new products. 

Thomas Reiher, director of Generative Design, MSC Software, said: “Designing an optimal product that fully exploits the available techniques is such a convoluted process today, that designers have to compromise. Designers’ eyes light up when they use MSC Apex Generative Design because it thinks like them, improving parts with intelligent engineering decisions – only much faster. 

“Our users have reported slashing their design time by 80% by reducing the number of individual tools and interventions, automating the optimisation process and streamlining their workflows. They start producing products that for the first time they have been able to optimise with design, performance and cost all tailored to their technical and commercial requirements.”

MSC Apex Generative Design can run on a normal laptop to generate initial candidates within an hour, and produce a final design within hours. The tool is also equipped with an intuitive interface, opening its capabilities up to designers and engineers without specialised knowledge of computer aided engineering. Design goals can be set up directly, or set against an existing design from Computer Aided Design (CAD) or directly from CAE models.

MSC Apex Generative Design’s ability to anticipate design issues that would otherwise require redesign much later in the process is particularly important for new manufacturing practices such as additive manufacturing. 3D printing teams can use the solution as a Design for Additive Manufacturing (DfAM) tool. It performs topology optimisation and intelligent smoothing in one step, producing parts with low distortion risk and ‘bionic’ printable geometries. The resulting parts are automatically designed for performance, balancing the material use with strength requirements and stress distribution.

Users can link MSC Apex Generative Design with manufacturing simulation tools Simufact Additive for metals and Digimat AM for polymers to make use of materials at every step.
