16 GB RAM. This is sufficient for student projects and small, steady-state flowsheets.
HYSYS is a CPU-bound application. The GPU is only used for:
Don't run HYSYS on an underpowered laptop. You will crash during large recycle loops or dynamic simulations. 16 GB RAM + SSD + 8-core CPU is the safe minimum for real engineering work.
Dedicated GPU with at least 4 GB VRAM (e.g., NVIDIA GeForce RTX 3050 / 4050 or NVIDIA T600/A1000 workstation cards). Aspen Hysys System Requirements
You don't need a gaming card, but a dedicated GPU helps the 3D modeler run smoothly when you're designing columns.
Sarah started typing a list of "Must-Haves" for his next upgrade request:
For a smooth experience, especially when building complex plants or using rate-based modeling, a mid-to-high-end workstation is recommended. Minimum : Intel Core i5 family (2.8 GHz) or faster. 16 GB RAM
If your organization uses a concurrent network license, a stable Local Area Network (LAN) or Virtual Private Network (VPN) connection to the AspenTech License Server is required.
Aspen HYSYS operates within a strict software ecosystem. Ensuring compatibility with your operating system and supporting software is vital to prevent installation errors. Windows Operating System
Administrator privileges are typically required for installation and to configure the Software License Manager (SLM) 3. Virtualization & Cloud Virtual Machines (VMs): The GPU is only used for: Don't run
