If your computer runs out of RAM while HYSYS is solving a massive flowsheet, Windows will resort to using your hard drive as "virtual memory." This causes the software to crawl or freeze.
While Aspen HYSYS is not a 3D rendering software, its visual flowchart interface, 3D piping view, and conceptual design tools require dedicated graphical processing to avoid interface lag.
Note: Home editions of Windows are not officially supported by AspenTech and frequently experience installation errors due to missing administrative and networking components. 2. Hardware Requirements: Minimum vs. Recommended
While HYSYS supports multi-threading, higher processor speed (GHz) generally provides better performance for steady-state simulations. For dynamic modeling, more cores are beneficial. 3. Memory (RAM) Minimum: 16 GB RAM. Aspen Hysys System Requirements
| 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) |
16 GB RAM. Suitable for small, steady-state simulations with limited components.
High-definition (1920 x 1080 or 4K) monitors are highly recommended for complex, high-density PFDs (Process Flow Diagrams). 6. Network If your computer runs out of RAM while
: If running on a VM, the virtual environment must be allocated the same amount of RAM and CPU resources as a physical desktop. Internet Connection
Minimum 1280 x 1024; higher resolutions are better for large Process Flow Diagrams (PFDs).
Before you click "download," it is critical to understand that running a steady-state simulation is vastly different from running a dynamic simulation or an integrated workflow. Installing HYSYS on an underpowered machine leads to simulation crashes, slow convergence, and lost productivity. For dynamic modeling, more cores are beneficial
A 64-bit operating system is mandatory to manage the large memory requirements of complex Aspen HYSYS simulation files. 2. Processor (CPU) Minimum: 2.8 GHz Intel Core i5 processor or equivalent.
