AI Agents

Describe your problem, not your parameters

Two purpose-built agents handle the entire setup. The Mesh Agent analyses your geometry and configures cell sizing, refinement zones, and domain shape. The CFD Agent selects your turbulence model, boundary conditions, and solver settings. Just tell them what you’re simulating.

Geometry Intelligence

Upload CAD and know it’s simulation-ready

Automatic watertight and manifold checks on upload. Hole detection, degenerate face removal, normal fixing, and B-Rep level healing for STEP/IGES. Feature detection identifies wheels, propellers, and rotating parts automatically — so your MRF zones are set before you ask.

Built for real engineering

Every feature you need from a professional CFD tool, without the six-figure license or the week-long setup.

Block-Structured Adaptive Meshing

Block-AMR structured grids designed from the ground up for GPU solvers. Uniform block shapes give optimal cache coherence and thread utilisation, with adaptive refinement where it matters. Automated setup from CAD to simulation-ready mesh in minutes.

Multi-Region & CHT

Define fluid, solid, and porous regions with coupled interfaces. Frozen rotor, mixing plane, and sliding mesh for turbomachinery. Contact resistance for conjugate heat transfer.

GPU-Native Density-Based Solver

Compressible RANS solver built from scratch for GPU execution. Riemann flux schemes (HLLC, Roe, AUSM+, SLAU2), MUSCL/WENO reconstruction, SSP-RK3 time integration, and automatic CFL ramping. Turbulence via k-\u03c9 SST, Spalart-Allmaras, and k-\u03b5. Pressure-based coupling also available.

Named Surfaces & Boundary Conditions

Click to name boundary patches directly on your geometry. Assign inlet velocity, outlet pressure, wall roughness, moving walls with RPM, symmetry, and slip — per patch.

Refinement & Rotating Zones

Drop box, cylinder, or sphere refinement regions anywhere in the domain. Add MRF rotating zones for fans, propellers, and wheels with automatic detection.

Domain Builder

Auto-sized external domains in box, C-domain, O-domain, or cylinder shapes. Ground plane, symmetry, and configurable padding. Internal flow auto-detection for pipes and ducts.

Server-Side Post-Processing

Slice planes, isosurfaces, streamlines, vector glyphs, and point probes computed server-side on your full result set. Colormaps applied client-side for instant switching. No data downloads, no local hardware requirements.

Post-Processing & Visualisation

Streamline tracing with RK4 integration, slice planes, isosurfaces, and field colouring. Jet, coolwarm, and viridis colormaps. Mesh quality overlays for skewness and aspect ratio.

Automatic Report Generation

Generate PDF reports of your simulation results with a single click. Includes mesh statistics, solver settings, convergence history, and key flow field visualisations — ready to share with your team or clients.
