A dedicated card ensures that panning and zooming through massive PFDs remains fluid and lag-free. 4. Storage (SSD vs. HDD)
Never run Aspen HYSYS on a traditional mechanical Hard Disk Drive (HDD) if you can avoid it. Aspen Hysys System Requirements
Solid State Drive (SSD) is mandatory for a modern experience.
If you are a student or a casual user, a modern with 16GB of RAM will get the job done. However, if you are a professional working on dynamic simulations or massive integrated gas plant models , investing in a workstation with 32GB of RAM and an i9 processor will save you hours of processing time every week. Microsoft Edge or Google Chrome (for Aspen Help
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).
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) Storage (SSD vs
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).
Dedicated GPU with at least 4GB VRAM (e.g., NVIDIA Quadro or NVIDIA GeForce RTX series).
Intel Core i7/i9 or AMD Ryzen 7/9 (8 cores or more).
