Hysys System Requirements: Aspen

Aspen HYSYS is a application.

: Using an SSD (Solid State Drive) instead of a traditional HDD is highly recommended to significantly reduce loading times for complex thermodynamic models.

This machine will run a 500-stream dynamic gas plant simulation without crashing. Do not spend more on a GPU. Do not spend less on cooling.

If your existing computer does not meet these , consider using AspenTech's Cloud Engineering Environment (CEE) – a browser-based HYSYS that runs on their servers. It requires only a modern browser and 10 Mbps internet, bypassing local hardware limits.

Legacy versions requiring older Windows environments (Windows 7 or 10) and older .NET Frameworks. Hardware Requirements

Optimized for Windows 11, multi-core Intel/AMD processors, and high-RAM workstations. Aspen HYSYS is a application

Are you simulating or large dynamic/upstream processes ?

High-DPI (4K) monitors are supported, but Windows text scaling should be kept at 100% or 125% to prevent visual bugs in older Aspen interface menus.

Most corporate and academic licenses are "floating" licenses, served from a central license server on the network. Do not spend more on a GPU

A common misconception is that a 64-core processor will make HYSYS run 64 times faster. In reality, for a single user, HYSYS often relies on high rather than massive multi-threading. While multi-user environments benefit from more cores, an individual engineer is often better off with a high-frequency i7 or i9 than a lower-clocked Xeon with more cores. 3.
