Aspen Hysys System Requirements [better] Jun 2026

Office 2016, 2019, or 365 (32-bit Visio is specifically required for some legacy features). Database:

Dedicated NVIDIA GeForce RTX or RTX Workstation GPU

While Aspen Hysys utilizes multi-threading for certain tasks (like data regression and parallel solver execution), high single-core clock speed is vital for sequential modular solvers. Random Access Memory (RAM) Aspen Hysys System Requirements

Insufficient RAM will cause the software to freeze when handling large fluid packages or extensive flowsheets. 16 GB RAM.

Always use a 64-bit operating system. While some Aspen components have been available in 32-bit versions historically, 64-bit systems allow the software to access much larger amounts of RAM, which is essential for realistic industrial-scale simulations. Office 2016, 2019, or 365 (32-bit Visio is

: 100 MB/second minimum; Gigabyte network recommended for server connectivity.

Whether you are an IT administrator provisioning enterprise workstations or a process engineer upgrading your personal laptop, this guide details the exact hardware and software specifications required to run Aspen HYSYS efficiently. Minimum vs. Recommended System Requirements 16 GB RAM

Aspen HYSYS is a computationally intensive application. While basic steady-state simulations run on most modern chips, complex dynamics or large-scale refinery models require high clock speeds. Intel Core i5 or AMD Ryzen 5 (Quad-core).
