A dedicated card ensures that panning and zooming through massive PFDs remains fluid and lag-free. 4. Storage (SSD vs. HDD)
64 GB is advised if you are running HYSYS alongside other heavy hitters like Aspen Plus, AVEVA, or large Excel-based automation tools. 3. Graphics Card (GPU) Aspen Hysys System Requirements

64-bit Office (2019 or 365) is highly recommended. HYSYS uses Excel for many reporting functions and "Aspen Simulation Workbook" integration; mismatched "bitness" (e.g., 32-bit Excel on 64-bit HYSYS) often causes crashes. HDD) 64 GB is advised if you are
Aspen HYSYS is a computationally intensive application. While basic steady-state simulations run on most modern chips, complex dynamics or large-scale refinery models require high clock speeds. Intel Core i5 or AMD Ryzen 5 (Quad-core).
HYSYS isn't a video game, but its PFD (Process Flow Diagram) and 3D modeling environments (like the Flare System Analyzer) rely on decent graphics processing. Integrated Intel HD Graphics.
At least 20 GB of free space for the installation of the AspenONE suite, plus additional space for simulation backup files and scratch data. 5. Operating System & Software Compatibility AspenTech is strict about OS compatibility. OS: Windows 10 or Windows 11 (64-bit only).
