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.
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).
Intel Core i7/i9 or AMD Ryzen 7/9 (8 cores or more). Aspen Hysys System Requirements
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).
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. 64-bit Office (2019 or 365) is highly recommended
A dedicated card ensures that panning and zooming through massive PFDs remains fluid and lag-free. 4. Storage (SSD vs. HDD)
Solid State Drive (SSD) is mandatory for a modern experience. While basic steady-state simulations run on most modern
Never run Aspen HYSYS on a traditional mechanical Hard Disk Drive (HDD) if you can avoid it.
Finding the right hardware for is the difference between a smooth simulation experience and a frustrating afternoon of "Program Not Responding" screens. Because HYSYS handles heavy thermodynamic calculations and complex property packages, it is more taxing on your system than standard office software. 1. Processor (CPU) – The Most Critical Component
