The sample results, in the viewer you get with every run.
Two real runs from our sample report: a 90° bend and a reducer, 50 mm pipe, water at 4 m/s. Rotate them, zoom in, and switch the wall pressure, the mid-plane velocity and the streamlines on and off. No sign-in.

Drag to rotate, scroll or pinch to zoom, right-drag or two fingers to pan. The buttons in the corner switch each field on and off; the legend shows the last one you switched on.
90° bend, 50 mm
- Flow
- Water, 4 m/s at the inlet (0.007832 m³/s)
- Mesh
- 913,825 cells, wall layers at y+ ≈ 1 (average 1.04)
- Static pressure drop
- 5,294 Pa
- Loss coefficient K
- 0.663, on the inlet velocity
- Convergence
- Converged at iteration 226
Reducer, 50 mm to 25 mm
- Flow
- Water, 4 m/s at the inlet (0.007832 m³/s)
- Mesh
- 1,490,703 cells, wall layers at y+ ≈ 1 (average 1.33)
- Static pressure drop
- 152,899 Pa
- Total pressure drop
- 33,139 Pa
- Loss coefficient K
- 4.151 on the inlet velocity, 0.259 on the outlet velocity
- Convergence
- Converged at iteration 173
Most of the static drop is the water speeding up from 4 m/s to about 16 m/s in the smaller pipe. The total pressure drop is the energy the fitting actually loses.
What you are looking at
- Wall pressure
- Static pressure on the pipe wall, in pascals, relative to the outlet (set to 0 Pa).
- Velocity slice
- Flow speed on the mid-plane through the pipe axis, in metres per second.
- Streamlines
- Paths the water takes, coloured by its speed, in metres per second.
- Colour scale
- Each legend runs from the lowest to the highest value of that field in this run.
Both are end-to-end test runs on our own geometry (12 Oct 2026), solved and reported through the same steps as a customer job. The models here are the files those jobs produced, compressed for the web; the colours and ranges are unchanged. Pressure on the mid-plane is in the PDF report. Results are design guidance, not certification.
