For most engineering users:

. Higher resolutions (1920 x 1080 or better) are strongly recommended for viewing complex PFDs (Process Flow Diagrams).

Intel Core i7 / i9 or AMD Ryzen 7 / 9 (8 Cores or more, 3.5 GHz base clock, high Turbo Boost).

For corporate and academic settings, Aspen HYSYS relies on a network license manager.

32 GB or more, especially if running server-side models.

due to VPN drops or WiFi interference will cause HYSYS to freeze and prompt "License lost – save your work." Always use a physical Ethernet cable on critical simulations. Configure your firewall not to block Aspen License Manager (LMGRD.exe).

Windows Server 2019 or Windows Server 2022 (for network license configurations and multi-user server environments).

: Intel Core i5, i7, or Core Ultra CPU (2.8 GHz or faster recommended). Memory (RAM) is recommended for stable performance, though is the absolute minimum. Hard Disk Space : At least

This configuration allows you to run , EDR (Exchanger Design & Rating) , and Aspen Plus side-by-side.

Will you be running simulations or heavy dynamic simulations?

Note for Mac Users: If you use a Mac, you must run Aspen HYSYS via a virtual machine (like Parallels Desktop or VMware Fusion) or Boot Camp (on older Intel Macs) configured with a valid Windows Professional license. 2. Hardware Requirements: Minimum vs. Recommended
