Solving matrix algebra, thermodynamic calculations, or convergence loops.
Intel Core-i7 or Core Ultra for intensive multivariable optimization and dynamic modeling. Memory (RAM): Minimum: 8 GB for small, steady-state simulations.

Intel Core i7 or i9, or the latest Core Ultra CPUs. High clock speeds benefit steady-state calculations, while multiple cores are essential for parallel processing in large flowsheets. Memory (RAM): 8 GB for standalone engineering deployments. Recommended: Aspen Hysys System Requirements
8 GB is the absolute minimum to breathe, but 16 GB to 32 GB is the industry standard for production-level flowsheets.
Aspen HYSYS is CPU-intensive, but a proper GPU helps with 3D visualizations (e.g., Dynamic Depressuring, PFD views).
Hardware: match capability to complexity This public link is valid for 7 days
16 GB to 32 GB. Complex models with multiple unit operations or integration with other aspenONE products (like Aspen PIMS) heavily consume RAM. Storage (Disk Space): 80 GB to 100 GB of free space.
However, for quick reference, IT departments and academic institutions often summarize these requirements. The sections below compile the most commonly cited and officially vetted specifications for modern versions of Aspen HYSYS.
For optimal performance, AspenTech recommends the following system configuration: Can’t copy the link right now
If you have a specific version of Aspen HYSYS in mind, I can help you look for the official documentation for that exact release.
High-definition (1920 x 1080 or 4K) monitors are highly recommended for complex, high-density PFDs (Process Flow Diagrams). 6. Network
