ANSYS 2020 R1 includes enhancements to ANSYS Mechanical to help engineers design complex, highly nonlinear large models. This release also provides a highly streamlined workflow in ANSYS Fluent, allowing even novice engineers to quickly and easily perform complex multiphase simulations. Other product portfolio upgrades include dynamic new tools for ANSYS HFSS SBR + and ANSYS Maxwell that significantly improve the flow of electronic / electromagnetic design.
3D Design
Explore more designs quickly in ANSYS Discovery Live: Change the structural solver to improve the accuracy of simpler geometries and experience the newly introduced steady-state fluid solver. Get upfront design insights by adding manufacturing constraints and multi-analysis optimization for topology optimization capabilities.
With ANSYS Discovery AIM, it’s able to simulate rubber components with an easy-to-use and guided workflow. Structural material data has also been expanded, including orthotropic elasticity and simulation of composite laminates.

New automation capabilities in ANSYS Discovery SpaceClaim make it easy to create and modify geometry without the complex traditional CAD systems. Also, the addition minimum surface lattice improves the efficiency of additive manufacturing applications. 


ANSYS 2020 R1 provides electromagnetic field simulation solutions to help customers grasp engineering trends in the areas of autonomous driving, 5G connectivity, electrification, and energy efficiency. New features include:
  • ANSYS HFSS SBR + is able to provide a creeping wave physics for correlation analysis and location studies of installed antennas to improve accuracy into objects with curve properties.
  • EMI Xplorer in ANSYS SIwave helps to evaluate and mitigate potential board and package-level EMI issues before running simulations early in the design cycle.
  • ANSYS Maxwell enables harmonic response coupling to improve the accuracy of electromagnetic and NVH designs in electric vehicle power systems, transformers, turbines, and other motors.
  • ANSYS Cloud has been extended in ANSYS Electronics Desktop to include electrothermal simulation involving ANSYS Icepak. In addition, ANSYS Icepak supports steady-state or transient thermal analysis for a variety of low- and high-frequency applications.


Embedded Software
In ANSYS 2020 R1, ANSYS SCADE further accelerates the design and automation of code generation for automotive embedded control software that complies with ISO 26262 ASIL D. The ANSYS SCADE kit provides a user-friendly user interface (UI) in the SCADE kit difference module, improving the Simulink® importer, and provides new features for multi-rate and multi-core designs. ANSYS SCADE Test now enables interval inspections and speeds up robustness testing; ANSYS SCADE Vision provides users with a fast way to detect autonomous software (AV) perception software defects by looking for extreme conditions.

Most of the innovations of SCADE toolchain are also available and applicable to aerospace and defense software designers and developers. These innovative products aid shorten the time to achieve DO-178C embedded control software certification and achieve extremely high security. The new version continues to simplify the software design and workflow integration of the embedded avionics cockpit display system and fully covers the ARINC 661 standard.


ANSYS Fluent provides 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. With easy-to-use, task-based meshing workflows and Mosaic technology, complemented by the Fluent CFD solver, you'll get the best results.

Easier to use:
Simplified workflows facilitate multiphase simulation setup. A single tabbed pane organizes settings into a logical step-by-step process. In the standard gas-liquid pipe flow simulation, the new setting proved 25% faster than before.

More CFD solutions:

  1. Algebraic interface density (AIAD) models allow accurate simulation of complex multiphase flow regime transitions.
  2. Fine electrochemical models can optimize lithium-ion battery cells.
  3. The speed of harmonic analysis in ANSYS CFX has been doubled, and multiple fundamental frequencies can now be solved.
  4. You can set up and solve complex fluid-structure interaction problems faster and easier.


ANSYS 2020 R1 provides additional enhancements to improve the processing of complex, highly nonlinear, oversized models, allowing ANSYS Mechanical users to enjoy more than ever. Enhancements include:
  • New features directly in Mechanical help streamline workflows, including assigning cross sections to line bodies, post-processing of reinforcements, and easily drag-and-drop external models. The topology optimization verification workflow has been improved, so you can now go directly from refining the best shape to meshing and verifying the final design. The fluid dynamic analysis tool ANSYS AQWA has all been migrated to Mechanical and new technologies have been added. For example, Generated load can be transferred to other analysis systems.
  • Enhanced integration of LS-DYNA with ANSYS Mechanical interface
  • ANSYS Sherlock reduces solution time. The tool uses ANSYS MAPDL as its default finite element analysis (FEA) engine, while enhancing application settings and improving the ability to configure multiple part libraries


Accurate materials information is critical for any product development organization, particularly aiming at organizations that are interested in popularizing simulation applications. In ANSYS 2020 R1, ANSYS GRANTA MI improves user experiences and supports the introduction of the gold standard corporate materials information management system across large engineering companies. With GRANTA MI, you can ensure consistency, reduce risk, increase efficiency, and drive innovation.

The new product ANSYS GRANTA MI: Pro is an easy-to-implement, professional version of GRANTA MI designed to provide quick-start options for design and simulation teams.
