GPU-accelerated CFD.
Ansys Fluent on H100 & RTX 6000 Pro.
Solve large Ansys CFD meshes 5–20× faster than CPU clusters. Submit a job, specify your element count, and Coreframe's GPU infrastructure handles the rest — no hardware to procure, no licences to manage. Per-job pricing, hosted in Bengaluru.
Why GPU matters for CFD
5–20× faster solve times
Ansys Fluent's GPU solver offloads the pressure-velocity coupling and linear algebra to thousands of CUDA cores in parallel. What takes 8 hours on a CPU cluster resolves in minutes on an H100.
VRAM determines mesh ceiling
The number of elements your solver can hold in memory is bounded by GPU VRAM. RTX 6000 Pro gives 96 GB GDDR7 — enough for most industrial meshes up to ~80 M elements without decomposition.
Memory bandwidth for convergence
Each solver iteration moves the full mesh state across memory repeatedly. H100's 3.35 TB/s HBM3 bandwidth keeps iterations fast even for large turbulent flow problems.
No idle hardware cost
A dedicated H100 workstation costs ₹50–80 lakh upfront, then sits idle between jobs. Per-job cloud billing means you pay only when the simulation is actually running.
GPU options
Building wind loads, HVAC, electronics cooling, external aero up to medium scale
Full-aircraft aerodynamics, large-scale combustion, parametric sweeps, transient simulations
Simulation types
Coreframe × Ansys
Coreframe is partnering with Ansys to deliver CFD as a managed per-job service. Submit your simulation job — mesh file, solver settings, boundary conditions — and receive results without touching any infrastructure. Per-job Ansys HPC licence access is available through the partnership, or bring your existing Ansys licence (BYOL).
Partnership currently in onboarding. Contact us to join the early access programme.
Pricing
Priced per simulation job based on mesh element count — the primary driver of GPU memory and compute time.
Final pricing depends on element count, solver type, and estimated wall-clock time. Contact us with your .cas file or element count for an exact quote.
FAQ
Does Ansys Fluent support GPU acceleration?
Yes. Ansys Fluent has a dedicated GPU solver (available since Ansys 2022 R1) that offloads pressure-based steady and transient solving to NVIDIA GPUs via CUDA. Speedups of 5–20× vs CPU are typical depending on mesh size and turbulence model.
How many mesh elements can run on RTX 6000 Pro?
RTX 6000 Pro has 96 GB GDDR7 VRAM. Ansys Fluent's GPU solver requires roughly 1–1.5 GB per million elements for a double-precision k-ω SST case. Practically, meshes up to ~60–80 M elements fit comfortably within single-GPU memory.
Do I need my own Ansys licence?
Coreframe is partnering with Ansys to offer per-job HPC licensing as part of the service. You can bring your own Ansys licence (BYOL) or use per-job licence access through the Coreframe–Ansys partnership. Contact us to discuss which model fits your workflow.
How is CFD job pricing calculated?
Pricing is based on mesh element count (the primary driver of memory and compute cost), GPU tier (RTX 6000 Pro vs H100), and estimated solve time. Contact Coreframe with your .cas file or element count for an accurate quote.
