What actually happens to the fuel inside a race car tank on the track?

In this case study, we fed real braking, cornering, and acceleration data from a private session at the Lausitzring directly into a transient CFD simulation.

Four tank configurations were tested against the same track curves and therefore the same forces.

Swipe through to see how no baffles, static baffles, flap baffles, and the newly added anti-slosh foam (aka porous media) compare under real race conditions, and which design kept the pickup covered almost continuously throughout the lap 👉

Driver's side and passenger's side in the same car, with the same rain, with different behavior.

On the passenger side, water distribution across the side window is relatively even. On the driver's side, it's periodic, fluid builds up and clears in direct sync with the wiper cycle.

Once you see it in the simulation it makes complete sense. The wiper geometry and rotation pattern create a fundamentally different flow condition on each side. The driver's window is more exposed to the wiper's influence, the passenger's less so.

Seeing both sides run together makes the cause obvious, not just the effect. And catching these kinds of behaviors early in a development cycle leaves you room to act before the design is fixed.

Take a first look at one of our newest products: shonEM, an electromagnetic simulation tool for electric motor analysis, still in early development.

The idea: set up your stator, rotor, and shaft geometry, define your materials and winding configuration, then run the simulation and get magnetic vector potential and torque results directly in the same environment. A Python script editor is built into the workflow, so you script once and run it as often as you need. Symmetry options let you choose between a full machine or a reduced sector, which controls your computational cost without changing the setup.

Two speeds, two completely different fluid regimes.

At 10 m/s, the wiper movement dominates. You can see it directly in the results, where the fluid on the side window increases and decreases in sync with each wiper stroke. The aerodynamic flow field is present, but the wipers have more influence on the overall behavior.

At 25 m/s, the flow field around the car takes over. Rivulets form at the A-pillar and move across the side windows.

That shift in dominant behavior is not something you can predict from a single test condition. It only becomes visible when you compare across a speed range.
How do you and your team decide which working conditions should be tested?

Making a geometry simulation-ready is rarely the quick step everyone hopes it will be.

shonMesh is built from the simulation engineer's point of view: how do you streamline the process and get your geometries ready as fast as possible? Three things make the difference between a mesh tool and a mesh workflow.

The first is geometry clean-up. Raw CAD geometry is rarely simulation-ready. shonMesh has a dedicated geometry repair and feature processing engine that handles the cleanup before meshing starts, not as an afterthought.

The second is mesh quality. High-quality tetrahedral volume meshes and boundary layer control are not optional for accurate CFD or FEA results. shonMesh gives you direct control over both.
The third is automation. Python scripting and script recording mean repetitive meshing workflows don't stay repetitive. Build it once, record it, run it on the next geometry.

Geometry repair, mesh quality, and automation, shonMesh is built around all three.

An 10 m³ of liquid. Emergency braking from 80 km/h to a full stop. What happens inside the tank?

Without baffles, the full fluid mass hits the front wall as a single coherent wave. And when the truck stops, the fluid doesn't. It keeps sloshing back and forth for several seconds, generating alternating forces on the tank walls at zero vehicle speed.

That causes vehicle stability problems.

Speed changes everything in exterior water management.

At low speeds, water behaves relatively predictably. It moves across the windshield, the wipers handle it, and very little reaches the driver's side window. At higher speeds, the picture shifts. Aerodynamic pressure starts to dominate, the flow bends toward the car, and water can track toward the driver's line of sight.

The point is that different conditions bring different physical effects into play. What governs the behavior at one operating point may be irrelevant at another, and a single test rarely captures the full range.

This is where simulation helps. It lets you explore many working conditions early, before the hardware exists, so you can find the critical ones instead of discovering them late.

Good pre-processing is never a single problem. It depends entirely on what comes after it, and different solvers need different meshes.

shonMesh covers both: it cleans up and repairs your geometries, and it meshes them for three applications. Surface meshes, for example as input for shonDy. Tetrahedral volume meshes for FEA, such as shonTA. And newly, FVM-CFD meshes, shown in the video.

One environment for all three, no switching tools or reformatting outputs. If your team works across structural, fluid, and thermal analysis, shonMesh gives you one tool and one workflow for all of it.

There is no gold standard for visualization. It always depends on what you want to show and emphasize.

Here, number density was our choice. This value tells you how many neighbors a particle has, which gives you direct visual feedback on where the fluid is clustering and where it thins out.

For exterior water management, that distinction is a big deal. A thin film behaves very differently from a concentrated rivulet, and that difference is exactly what determines whether water reaches the driver's line of sight or clears the A-pillar cleanly.

But the fact that it is the best choice here doesn't mean it is always the best choice. How do you decide which metric tells the story best for people outside the team?

Thermal analysis just got faster.

Simulating heat distribution across a full transmission assembly, every bearing, every housing, every shaft, is one of the most complex workflows in drivetrain engineering.

shonTA handles it in one environment. Multi-component setup, transient and steady-state results, and a system diagram that maps every thermal interaction across the full assembly.
