Aspen Hysys System Requirements ((full))

When in doubt, over-spec your memory and verify your CPU’s single-thread performance on PassMark or Cinebench R23 (aim for >2000 points single-core). Your simulation convergence times – and your sanity – will thank you.

32 GB or higher (64 GB+) is recommended for users working with large flowsheets, thermodynamics-intensive models, or dynamic simulations to avoid excessive disk swapping. 4. Hard Disk Space (Storage) Minimum: 100 GB of free space. Aspen Hysys System Requirements

Aspen HYSYS is validated primarily for Microsoft Windows. The software runs on: When in doubt, over-spec your memory and verify

A single large-scale refinery simulation with a thermo package like Peng-Robinson can easily consume 18-22GB of RAM. Adding a dynamic pressure relief scenario pushes that to 30GB+. The software runs on: A single large-scale refinery

Typically requires version 4.8 or higher.
