HYSYS uses FlexNet licensing. You have two options:
Insufficient RAM forces your computer to use virtual memory on the hard drive, severely degrading simulation speeds.
Uses a local hardware dongle or a locked standalone file on your machine. Aspen Hysys System Requirements
: 80 GB to 100 GB of free space for the installation alone.
Running light simulations differs wildly from conducting plant-wide steady-state or dynamic modeling. Below is a breakdown of the standard hardware specifications across different user profiles. V8.7 aspenONE Minimum Hardware Requirements - AspenTech HYSYS uses FlexNet licensing
While the installer might let you proceed with less, the official AspenTech platform support generally targets these benchmarks for a stable experience:
: 16 GB to 32 GB for large-scale industrial modeling. Storage (Hard Drive Space) : 80 GB to 100 GB of free space for the installation alone
🔹 Works on VMware ESXi or Hyper-V, but not recommended for real-time dynamics due to timer latency.
Aspen HYSYS is the industry-standard process simulation software used by chemical, petroleum, and gas engineers worldwide. Because it handles complex thermodynamic calculations, dynamic modeling, and large-scale flowsheet simulations, running the software smoothly requires a robust computer setup.
