CFD simulation, built for exploring

See how your plant behaves before you build it

We run high-fidelity CFD simulations of your equipment and turn the results into decisions your team can act on, not one more report forgotten in a folder.

See the demoTalk to an engineer

How it works

From geometry to decision in four steps

  1. 01

    Send your geometry and your goals

    Share CAD models or drawings along with the operating conditions and the questions you need answered.

  2. 02

    We run the simulation

    Our engineers build and validate a CFD model, running the range of scenarios that matters to your decision.

  3. 03

    You get results you can trust

    A clear report, visualizations and specific recommendations, not just raw solver output.

  4. 04

    Iterate with confidence

    Explore design variants quickly, backed by simulation, before you commit to physical changes.

Will your pump sump form a vortex?

A real example of how we work: predicting suction vortices in a pump sump, based on a published benchmark experiment. Drag the controls to change the flow rate and the water level, and watch the risk verdict update.

Schematic side elevation, benchmark geometry (450 × 300 mm passage, 150 mm outer-diameter suction pipe). Not to scale.

Operating envelope

Where this sump can run without forming a vortex, the whole design space, not just the point you picked.

Based on the critical-submergence lines fitted in Okamura et al. (2007), expressed in Froude form. Measured on the benchmark model only and carried over here by Froude similarity as an indication, not as a validated criterion. On a real project we use TSJ S002 / ANSI/HI 9.8, or run the full transient CFD case.

3D simulation result

Benchmark case 1 — Okamura et al. (2007), Table 1

These images are the solved result for your current settings: Q = 1.00 m³/min, H = 230 mm.
3D streamlines of the approach flow accelerating into the suction bell
Approach flow. Streamlines seeded across the inlet, colored by velocity magnitude (0–1.5 m/s). The flow accelerates around and under the bell and rises up the pipe with visible swirl.
3D vortex visualization showing streamlines spiralling into the suction pipe
Suction vortices. Streamlines seeded from the free surface near the pipe. Where one spirals down into the bell, a vortex is forming. The pale shapes are the Q-criterion envelope; the red markers are the detected core positions.

Coarse mesh, 1,500 iterations. Steady RANS does not fully converge on this flow, the vortex cores genuinely move, so the velocity field is settled but vortex strength is reported as a range across the writes.

Deliverables

What you actually walk away with

Simulation report

Results, assumptions and validation against your operating data, written for engineers and for the people who decide.

3D visualizations and animations

Flow fields, temperature maps and pressure losses you can share internally or with stakeholders.

Design recommendations

Concrete changes ranked by expected impact, not just "here is what happens".

A reusable simulation model

A model you can bring back to us (or to your own team) to explore future design changes faster.
