For steady-state simulations, single-core performance (high GHz) is more critical than having dozens of cores. Look for a base clock speed of 3.0 GHz or higher , with turbo boost reaching 4.5 GHz+. Stick with V11
Do not install HYSYS on a mechanical HDD (Hard Disk Drive). The SOLVER engine uses thousands of temporary iterative files. On an HDD, a simulation that converges in 10 seconds will take 4 minutes. The SOLVER engine uses thousands of temporary iterative
HYSYS is a CPU-bound application. The GPU is only used for:
Aspen HYSYS is built for the Windows ecosystem and requires specific security and administrative settings. Supported : Windows 10 (64-bit) or Windows 11.
For a standard desktop deployment, these are the recommended specifications for a smooth simulation experience:
