We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi,
As of 2023 R2, Ansys has ended support of Energico. If you require continued use of Energico and are not able to use a previously released version, please create a support request for the technical support team.

Regarding ERN, Chemkin might help you out there. Be sure to check out the following links:
1.2. Overview of the Chemkin Software (ansys.com)
1. New Features and Enhancements (ansys.com)

I hope this helps. Other members of forum can also chime in with their helpful insights.

Regards,
Harshvardhan
