ANSYS Simulation and Analysis Workstations – What Matters Most?
Ansys software has evolved significantly, and so have the demands it places on your hardware. Fluent, Ansys Mechanical, Discovery, HFSS, and LS-DYNA are all built for parallel processing, meaning core count, memory bandwidth, and GPU acceleration all play critical roles in simulation performance.
Our bespoke workstations are engineered to speed up solve times, grow with your needs, and give great value.
Choosing the Best CPU for Ansys
Ansys benefits greatly from multi-core processors, but core usage is often limited by licensing. For many workloads, the optimal setup is a careful mix of cores, clock speed, and cache.
We highly recommend the AMD Ryzen™ Threadripper™ PRO 7000 Series and the Intel® Xeon® W-3400 Series processors. These workstation-grade CPUs provide:
High core counts for multi-threaded workloads
Excellent per-core performance
ECC memory support
Robust PCIe lane availability for GPU and NVMe scalability
Expanded CPU Options: Dual CPU and Server-Class Processors
For users with highly parallel workloads such as large-scale CFD or electromagnetic simulations, or for those with significant HPC pack licensing, we also offer:
These enterprise-grade platforms offer extreme scalability—supporting up to 192 physical cores and very large memory setups—ideal for enterprise or academic environments with aggressive simulation needs.
Understanding Ansys Licensing: CPU, GPU, and HPC Packs
When setting up an Ansys workstation, licensing for CPU and GPU usage is an important consideration. By default, Ansys typically allows simulations to run on a limited number of CPU cores—often around four logical cores. To scale beyond that, HPC (High Performance Computing) packs are generally required.
GPU acceleration is supported in some Ansys solvers, such as Fluent, LS-DYNA, and Discovery, but may also involve separate licensing. In certain cases, GPUs are treated similarly to solver resources, and additional licences—such as HPC or GPU-specific features—may be needed to fully utilise them.
Not all solvers support GPU acceleration, and licensing requirements can vary depending on the solver version, hardware, and licence type.
Consult with Ansys or your software vendor to confirm licence options before finalising your workstation setup.
What Graphics Card (GPU) Is Best For Ansys in 2025?
Ansys’ support for GPU acceleration has matured rapidly. Many simulation tools within the Ansys suite now leverage CUDA-enabled GPUs to offload computation and deliver major reductions in solve time.
For optimal compatibility and performance, we recommend the latest NVIDIA RTX™ Ada Generation and NVIDIA RTX™ PRO Blackwell Series professional graphics cards. These workstation GPUs offer:
ECC memory for error resilience
FP64 (double-precision) performance important for accurate results
Certified drivers and stability for Ansys workflows
Recommended GPUs:
If you plan to run GPU-accelerated solvers, we recommend selecting the most powerful GPU your Ansys licence permits. For CPU-only workflows, an entry-level RTX A2000 or A400 is suitable for display and basic rendering needs.
Best Memory Configuration for an Ansys Workstation
Ansys workloads, particularly in CFD, meshing, and multiphysics, are extremely memory intensive. A lack of memory leads to paging, bottlenecks, and even simulation failure.
As a baseline, we recommend:
Minimum: 64GB DDR5 ECC Memory
Ideal: 128GB – 256GB depending on workload complexity
Memory Intensive: Up to 512GB+ for users running large-scale transient or multiphysics simulations
We also advise allocating at least 4–6GB of memory per CPU core, especially for Ansys Mechanical or Fluent solvers.
Memory Channels Matter
Modern workstation CPUs support quad- or eight-channel memory configurations. Our testing has shown that utilising all available channels with smaller-capacity DIMMs can yield speed gains of up to 20%. ECC (Error Correction Code) memory is strongly recommended to maintain simulation integrity and system reliability.
Storage Recommendations for Ansys 2025
High-speed storage is critical for Ansys, particularly during meshing, model import/export, and result post-processing phases.
Primary Drive (OS & Ansys Install)
Recommended: NVMe SSD (PCIe Gen 4 or Gen 5)
Capacity: 1TB minimum
Performance: Read/write speeds > 5,000 MB/s
Secondary Drive (Active Simulation Files)
Recommended: Dedicated NVMe SSD
Keeps your simulation data isolated from OS and application processes
Long-Term Storage
HDDs or large-capacity SSDs (SATA or NVMe)
Network Attached Storage (NAS) for team environments or backup
PCIe Gen 4 and Gen 5 NVMe drives now dominate the market, offering ultra-fast throughput ideal for heavy simulation tasks. Workstation Specialists workstations are fully compatible with the latest Gen 5 SSDs for futureproof performance.
Mobile Workstations for Ansys
Our WS-M IC-M Pro Mobile Workstation range is ideal for engineers and researchers who need to simulate on the move. Featuring:
Intel Core™ Ultra processors
NVIDIA RTX™ Professional mobile GPUs
DDR5 memory
PCIe Gen 4 NVMe storage
These laptops offer exceptional performance in a compact, robust chassis—perfect for pre/post-processing, geometry preparation, and even smaller simulations on the go.
