New autoskin features in Ansys Discovery SpaceClaim enable you to easily combine analytic geometry with autoskinned patches during reverse engineering. In addition, new minimal surface lattices increase efficiency in additive manufacturing applications.


Additive Manufacturing

Ansys 2020 R1 features major advances in additive manufacturing (AM) simulation capabilities throughout the AM product line:

  • Ansys Additive Prep features expanded capabilities in the build processor so you can change laser parameters. Building on its capability to write files to SLM machines, it now lets you write files to EOS machines.
  • Workbench Additive now offers inherent strain simulation in addition to thermal–structural additive simulation. Ansys Additive Print to Workbench Additive workflow for cutoff scenarios has been introduced.
  • Additive Print now supports J2 Plasticity. It also accepts laser beam inputs for the thermal solver.
  • Aluminum alloy AlSi10Mg has been validated for all simulation types in Additive Print and Additive Science.
  • Additive Print and Additive Science have been improved for increased accuracy and faster run times.



Ansys 2020 R1 delivers electromagnetic field simulation solutions to aid our customers’ pursuit of the engineering megatrends of autonomy, 5G connectivity, electrification and energy efficiency. New features include:

  • Ansys HFSS SBR+ offers creeping wave physics for installed antenna analysis and placement studies, thus increasing the accuracy of modeling antennas integrated into objects with curved attributes.
  • EMI Xplorer in Ansys SIwave helps to assess and mitigate potential board- and package-level EMI problems prior to running simulations early in the design cycle.
  • Ansys Maxwell enables harmonic force coupling, enhancing the accuracy of the electromagnetic and vibroacoustic design of electric vehicle powertrains, transformers, turbomachinery and other electric machines.
  • Ansys Cloud has been extended in Ansys Electronics Desktop to include electrothermal simulations involving Ansys Icepak. Additionally, Icepak supports steady-state or transient thermal analysis for a variety of low- and high-frequency applications.



Ansys Fluent offers a new experience that enables novice or expert users to run robust computational fluid dynamics (CFD) simulations in less time and with less training than ever before. Easy-to-use, task-based meshing workflows and Mosaic technology — coupled with Fluent’s CFD solvers — deliver great results, without compromise.

Easier to use

A streamlined workflow facilitates multiphase simulation setup. A single, tabbed panel organizes setup into a logical, step-by-step flow. In a benchmark gas–liquid pipe flow simulation, the new setup proved 25% faster.

More CFD solutions

  • An algebraic interface area density (AIAD) model accurately simulates complex multiphase regime transitions.
  • A detailed electrochemistry model optimizes lithium-ion battery cells.
  • Harmonic analysis in Ansys CFX is 2X faster and can now solve for multiple base frequencies.
  • Complex fluid-structure interaction problems can be set up and solved faster and more easily.



Accurate materials information is essential for any product development organization, particularly one aiming to make pervasive use of simulation. In Ansys 2020 R1, Ansys GRANTA MI has an enhanced user experience, which supports the rollout of the gold standard corporate materials information management system across large engineering enterprises. With GRANTA MI, you can ensure consistency, lower risk, increase efficiency and drive innovation.

A new product, Ansys GRANTA MI Pro, is an easy-to-implement, focused version of GRANTA MI, designed as a fast-start option for design and simulation teams. This product provides CAD and CAE users with direct access to reliable materials reference data from Ansys Granta, alongside managed lists of in-house materials and their approved properties.

Ansys 2020 R1 also enhances the data in the GRANTA Materials Data for Simulation dataset, available within Ansys Mechanical and Ansys Electronics Desktop.



Ansys Minerva improves the organization of product life cycle data. It facilitates version control, 3D visualization, collaboration and data reuse. New integration with high-performance computing (HPC) systems and CAE tools streamlines process challenges. The new release incorporates enhancements to dashboards, configuration management, metadata handling, the Ansys Workbench client connector and job submission workflow, and project updating in Ansys optiSLang.



Ansys 2020 R1 empowers Ansys Mechanical users to go further than ever before with enhancements to improve the handling of complex, highly nonlinear and massively large models.

Enhancements include:

  • Additional functionality directly in Mechanical for streamlined workflows, including cross sectional assignments for line bodies, post-processing of reinforcements and easy drag-and-drop external models
  • Improved topology optimization validation workflows so you can now go directly from a tessellated optimal shape to meshing and validation of the final design
  • Full migration of Ansys AQWA, a hydrodynamic analysis tool, into Mechanical, including new technology such as the ability to transfer generated loads to other analysis systems
  • Enhanced integration of LS-DYNA into the Ansys Mechanical interface following our recent acquisition of LSTC
  • Quicker solve times in Ansys Sherlock, which now uses Ansys MAPDL as its default FEA engine, along with consolidation of application settings and the ability to configure multiple part libraries



Ansys 2020 R1 contains two new systems solutions: Ansys VRXPERIENCE Light Simulation and Ansys medini analyze for Cybersecurity, along with a new Battery Wizard in Ansys Twin Builder.

VRXPERIENCE Light Simulation makes the illumination of automotive product designs easier. It combines visual design and advanced engineering review by connecting Autodesk VRED design visualization software and Ansys’ physics-based lighting simulations. The result is a photorealistic visualization of vehicle interior and exterior lighting.

Ansys medini analyze for Cybersecurity provides systematic analysis and assessment of security threats to cyber–physical systems, starting early in the design stage. medini analyze also supports safety analysis of the intended functionality (SOTIF) of systems, which makes autonomy (autonomous vehicles, air taxis, etc.) possible.

With the Ansys Twin Builder Battery Wizard, you can easily construct battery cells and assemble them into battery modules. It also streamlines model creation and parameterization of ECM cells and modules.
