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. Part 7: Graphics Card (GPU) Requirements – A Common Mistake Many engineers buy expensive gaming GPUs (RTX 4090) for HYSYS. This is a waste of money.
University students running small homework simulations or testing property packages only. Part 3: Recommended System Requirements (The "Professional Standard") This configuration allows you to run dynamic simulations , EDR (Exchanger Design & Rating) , and Aspen Plus side-by-side.
Aspen HYSYS 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. Aspen Hysys System Requirements
| Component | HPC/Optimization Grade | | :--- | :--- | | | Dual Intel Xeon Gold 6438M (32 cores total) or AMD EPYC 9354 | | RAM | 128 GB to 256 GB DDR5 ECC Reg | | Storage | RAID 10 NVMe SSDs (Read speed > 5000 MB/s) | | GPU | NVIDIA RTX 5000 Ada (For Aspen Simulation Workbook 3D) | | Cooling | Liquid cooling (Closed-loop) |
A single large-scale refinery simulation with a thermo package like Peng-Robinson can easily consume 18-22GB of RAM. Adding a dynamic pressure relief scenario pushes that to 30GB+. Part 4: High-Performance Computing (HPC) & Optimization If you run rate-based distillation , column hydraulics , or parallel batch simulation , you need enterprise hardware. Do not install HYSYS on a mechanical HDD (Hard Disk Drive)
| Component | Minimum Requirement | | :--- | :--- | | | Windows 10 Enterprise/Pro (64-bit) Build 21H2+ | | CPU | Intel Core i5 (8th gen) or AMD Ryzen 5 3500 | | RAM | 8 GB DDR4 | | Storage | 25 GB free SSD (NVMe preferred) | | Display | 1920 x 1080 (Full HD) | | GPU | Integrated Intel UHD Graphics (no dedicated card needed for basic use) |
This machine will run a 500-stream dynamic gas plant simulation without crashing. Do not spend more on a GPU. Do not spend less on cooling. If your existing computer does not meet these Aspen HYSYS system requirements , consider using AspenTech's Cloud Engineering Environment (CEE) – a browser-based HYSYS that runs on their servers. It requires only a modern browser and 10 Mbps internet, bypassing local hardware limits. Part 7: Graphics Card (GPU) Requirements – A
| Installation Type | Disk Space Required | | :--- | :--- | | | 15 GB | | HYSYS + Aspen Plus + EDR | 35 GB | | Full Suite (Plus, HYSYS, Dynamics, Flarenet, Utilities) | 85+ GB | | Temporary extraction space | 50 GB (The installer unpacks huge CAB files) |
