3D Design

This release introduces Ansys Discovery, the first product design software to combine instant physics, proven high-fidelity simulation and interactive geometry modeling into a single, radically easy-to-use interface.

Users can now explore large design spaces and answer critical design questions early in the product design process, without waiting days or weeks for traditional simulation results. Discovery seamlessly combines direct human-driven interaction with generative algorithms to inspire new designs — and embeds multiphysics simulation to provide both rapid and accurate product insights.

Ansys SpaceClaim updates that support concept modeling and model prep for simulation include: block recording and bidirectional CAD interfaces to allow import of modified CAD geometry; constraint-based sketching that makes it easier to create complex sketches for 3D design; and autoskinning of topology optimization results from Ansys Mechanical for automated geometry reconstruction.

Additive Manufacturing

New features in the Ansys Additive Suite enable you to add user-defined materials and import EOS build files. Also, improvements have been made to the Print to Workbench workflows for simulating cutoff, heat treatment and other advanced scenarios.

  • In Ansys Additive Science, you can now define your own material parameters. For example, penetration depth and absorptivity are required internal inputs that are generally unknown and vary based on other process parameters. With the user-defined material capability, you can examine trends and create new materials that account for these variations in absorptivity and penetration depth.
  • Ansys Additive Print includes directional cutoff using MAPDL as the solver.
  • EOS machine build files can now be imported into Additive Print.
  • Additions to Additive Prep include automatic collision checks for part-free areas, multiple supports on a single part region and the ability to export CLI files.


Ansys 2020 R2 delivers materials information improvements to help you build better products using digitalized materials knowledge. New features include:

  • Materials data ready for simulation in more Ansys solvers: the extension of Materials Data for Simulation (MDS) to Ansys Discovery Live and Ansys Fluent comes with even more simulation-ready data for Ansys Mechanical and Ansys Electronics Desktop.
  • Materials data management integration with Creo design tools in Ansys GRANTA MI Pro, building on the existing cross-platform support for CAD and CAE with Siemens NX™ and Ansys Workbench.
  • Significantly enhanced usability in Ansys GRANTA MI Enterprise with a unified user-interface and enhanced integration to Ansys Minerva and other enterprise systems.
  • Updated versions of the latest materials datasets for restricted substances, MMPDS and ASME, together with improved integration between Ansys GRANTA Selector and GRANTA MI Pro.
