ANSYS Workstation PCs
ANSYS is one of the most powerful engineering simulation platforms in the world, used across aerospace, automotive, energy, and manufacturing industries to predict how products behave under real-world conditions. From Computational Fluid Dynamics (CFD) to Finite Element Analysis (FEA) and Multiphysics simulations, ANSYS demands carefully balanced, high-performance hardware.
Titan Computers builds workstations optimized for ANSYS workloads, ensuring maximum stability, scalability, and simulation throughput.

CPU Recommendations for ANSYS
Selecting the right processor for ANSYS depends on both your simulation type and your licensing model:
Licensing limits: Standard ANSYS Mechanical licenses allow up to 4 CPU cores. To use more, HPC Pack licenses must be purchased, scaling up the number of usable cores.
Simulation type:
FEA (Finite Element Analysis): Often benefits more from high single-core clock speed. A fast Intel Core i9 or AMD Ryzen 9 (816 cores, ≥5.0 GHz boost) is ideal for many design-stage workloads.
CFD (Computational Fluid Dynamics): CFD solvers scale more efficiently across many cores. If running large models, AMD Threadripper Pro (2464 cores) or Intel Xeon W processors with HPC licenses provide faster solve times.
Multiphysics or enterprise-scale runs: For massive parallel workloads, dual-socket Xeon or EPYC systems may be justified in cluster-like configurations.
Summary: For general users, prioritize clock speed first. For CFD-heavy users with HPC licenses, prioritize core count.
GPU Recommendations for ANSYS
While ANSYS is still primarily CPU-driven, GPUs play an increasingly important role in visualization and some solvers (e.g., ANSYS Discovery Live).
Recommended GPUs in 2025:
- Entry / design visualization: NVIDIA RTX 4000 Ada Generation (1620GB VRAM).
- High-end solvers & visualization: NVIDIA RTX 5000 / RTX 6000 Ada Generation (2448GB VRAM).
- GPU-accelerated workloads (Discovery, Fluids with GPU support): Prioritize workstation-class cards with certified drivers.
Note: Consumer GPUs (GeForce RTX) may appear cost-effective, but for ANSYS stability and driver validation, professional-grade GPUs are strongly recommended.
RAM Recommendations for ANSYS
ANSYS simulations are memory-intensive, particularly CFD and structural analysis with large meshes.
- Minimum: 64GB RAM for light/medium projects.
- Recommended for FEA: 128GB RAM for stability with larger models.
- Recommended for CFD / multiphysics: 256GB512GB RAM for advanced or enterprise workloads.
- Scalability: Choose a platform (AMD Epyc or Xeon 6) that supports 8-channel+ memory for maximum bandwidth.
Storage Recommendations for ANSYS
Large simulation datasets demand fast and reliable storage.
- Primary Drive (OS + ANSYS): NVMe SSD (PCIe 4.0/5.0), 1TB minimum.
- Simulation Scratch & Working Data: Secondary NVMe SSD (2TB+) for temporary files and solver writes.
- Project Archive: High-capacity enterprise HDDs or RAID storage (8TB16TB+) for long-term data retention.
- Backup: RAID-protected NAS or external backup solutions are strongly recommended.
