We have been on CARE Business for one year and just recently renewed for another year. The major benefits we see are the prompt responses of the support team, which in combination with the Training Portal are very helpful ways to resolve issues and give good tips. The Weld and Bolt toolkit for Ansys Mechanical offers many possibilities and we are aiming to set up a simulation report template with the Report Generator app. Looking ahead, we are aiming to explore the compute power of CloudConnect and Rescale which also comes with the CARE Program. We are in the process of building an analysis team. We believe the partnership which comes with CARE will be an asset during this process as well as future initiatives.

The CARE Program has been valuable for us, providing additional resources and guidance when needed. It has been particularly helpful in instances where we've encountered more complex computational fluid dynamics problems. What we appreciate about the program is the support we've received when we've faced challenges. This has been useful in helping us keep our projects moving forward.

Ansys Granta Selector™ has given us more knowledge about the environmental impact of our products and where we should focus our attention in the development of new ones. Ansys Granta Selector also helped us to verify whether it is sustainable for us to gather used filters from customers to optimize the recycling process.
