An NVMe SSD is non-negotiable. Loading those libraries from an old spinning hard drive is like reading a book through a straw.
Local installations of Microsoft 365 apps are supported, but cloud-only versions cannot link directly via OLE/COM interfaces. Database and Prerequisites
For a smooth experience, especially when building complex plants or using rate-based modeling, a mid-to-high-end workstation is recommended. Minimum : Intel Core i5 family (2.8 GHz) or faster.
If your organization uses a concurrent network license, a stable Local Area Network (LAN) or Virtual Private Network (VPN) connection to the AspenTech License Server is required. Aspen Hysys System Requirements
16GB is the bare minimum. For heavy fluid packages and huge heat exchanger networks, go for 32GB or 64GB.
is the gold standard for process simulation in the oil, gas, and chemical industries. Whether you are designing a new refinery, optimizing a gas plant, or conducting safety analysis, HYSYS demands significant computational resources.
Dedicated NVIDIA GeForce RTX or RTX Workstation GPU An NVMe SSD is non-negotiable
Aspen HYSYS uses a floating license manager (FlexNet). Even with a local license file, the software phones home.
Modern versions of Aspen HYSYS only run on 64-bit operating systems.
Uses a local hardware dongle or a locked standalone file on your machine. 16GB is the bare minimum
Aspen HYSYS is primarily for most calculations, though certain operations (property generation, reporting, optimization) leverage multiple cores.
While the installer might let you proceed with less, the official AspenTech platform support generally targets these benchmarks for a stable experience:
| Operating System | Supported Versions (as of HYSYS V14) | Notes | |----------------|---------------------------------------|-------| | | 2019, 2022 | Preferred for network license servers and remote desktop deployments. | | Windows Client | Windows 10 Enterprise/Pro (64-bit) 21H2+; Windows 11 Pro/Enterprise | Home editions are not supported (domain and security policy limitations). | | Windows 8.1 | No longer supported (V12.1 and earlier only) | Security risks, no modern driver support. | | Windows 7 | Not supported (EOL) | Will not install on V13 and above. |
