If you’ve ever tried running a simulation on ANSYS only to watch your computer crawl, you already know that system requirements are no joke. Whether you’re an engineering student learning the ropes or a professional working with massive CFD or structural models, your hardware can make or break your workflow.
In this guide, we’ll break down the minimum, recommended, and high-performance system requirements for ANSYS in 2025—and explain them in plain English. By the end, you’ll know exactly what kind of laptop or workstation you should be looking for.

Why System Requirements Matter for ANSYS
Unlike lightweight apps, ANSYS is extremely demanding. Most solvers rely on CPU cores, some take advantage of GPU acceleration, and almost all eat up a ton of RAM. Using the right hardware means:
- Faster solve times
- Fewer crashes
- Smoother workflow when handling big models
Minimum vs. Recommended Specs
Here’s a quick breakdown:
| Requirement Level | CPU | RAM | Storage | GPU |
|---|---|---|---|---|
| Minimum (student/small projects) | 4–6 cores | 8–16 GB | 100 GB HDD/SSD | Basic GPU with OpenGL support |
| Recommended (medium projects) | 6–16 high-frequency cores | 32–64 GB | 1 TB SSD (NVMe preferred) | Workstation GPU (NVIDIA RTX/Quadro, AMD Pro) |
| High-End (large models/HPC) | Multi-core Xeon/Threadripper | 128 GB+ | NVMe + fast scratch disks | Data-center GPU (NVIDIA A100, AMD Instinct) |
A Closer Look at Each Component
1. CPU: Speed or Cores?
ANSYS uses both, but single-thread speed still matters a lot for pre-processing and certain solvers.
- Students: go for Intel i7/i9 or AMD Ryzen 7/9.
- Professionals: Xeon, Threadripper, or high-core Ryzen if you run parallel jobs.
2. RAM: Don’t Skimp
As a rule of thumb, the bigger your mesh, the more memory you’ll need.
- Small projects: 16 GB may work.
- Professional work: 32–64 GB is the sweet spot.
- Large CFD/structural models: 128 GB or more.
3. Storage: SSDs Are a Must
Traditional hard drives will bottleneck your workflow. Always go for SSDs, preferably NVMe.
- At least 1 TB for professionals handling multiple projects.
4. GPU: More Than Just Graphics
Not every ANSYS solver uses the GPU, but Discovery and Fluent (with GPU acceleration) can really benefit.
- For Discovery and visualization: NVIDIA RTX/Quadro or AMD workstation cards.
- For GPU solvers: data-center GPUs like NVIDIA A100 or RTX Ada cards give a huge performance boost.
Product-Specific Notes
- ANSYS Discovery → Needs a strong GPU for real-time simulation.
- ANSYS Fluent (GPU solver) → Loves high-end NVIDIA cards, but you’ll need the right license.
- ANSYS Mechanical → CPU- and RAM-heavy; GPU matters less except for visualization.
- ANSYS Student → Lighter, but still happier with a decent laptop.
Suggested Setups (2025)
- For Students → Laptop with Intel i7/Ryzen 7, 16 GB RAM, 512 GB SSD, NVIDIA RTX 3050 or better.
- For Professionals → Workstation with Ryzen 9/i9, 64 GB RAM, 1 TB NVMe SSD, NVIDIA RTX 4000 series (or AMD equivalent).
- For HPC Enthusiasts → Multi-core server CPU, 128 GB+ RAM, multiple NVMe drives, NVIDIA A100 or AMD Instinct GPUs.
Final Thoughts
If you’re serious about simulations, treat your hardware as part of your toolbox. You wouldn’t build a house with a flimsy hammer—same goes for ANSYS. Start with the recommended requirements, and if your projects are growing, invest in high-performance gear.
FAQs
Yes, but only small projects. For serious work, get at least 16 GB RAM and a dedicated GPU.
Not natively. You’d need Boot Camp or a virtualized Windows/Linux setup.
For Discovery and Fluent GPU solvers, yes. For basic Mechanical simulations, not so much.
