Aspen Hysys System Requirements May 2026

As late as 2018, HYSYS could run on a 7200 RPM HDD. That era is over. Modern versions (V12+) create multiple temporary files, log files, and autosave backups.

Recommended: Two drives – C:\ for OS and software (1TB NVMe), D:\ for active projects (2TB NVMe).

Aspen HYSYS relies on several Microsoft components. The installer typically handles these, but manual verification is wise. Aspen Hysys System Requirements

Verdict: If you run dynamic simulations for more than 30 minutes daily, buy a desktop. A laptop will thermal throttle and frustrate you.

Aspen HYSYS is a leading process simulation software used extensively in the oil, gas, and chemical industries. The system requirements vary significantly based on the scale of the simulation (e.g., a single column vs. a full plant with dynamics). This report outlines the minimum requirements for installation, the recommended requirements for stable operation, and the optimal requirements for large-scale or dynamic simulations. As late as 2018, HYSYS could run on a 7200 RPM HDD

Aspen HYSYS installations are large, and simulation files can grow significantly, especially with dynamic results.
