Preventing Thermal Failure in EDU Design
Electric Drive Units (EDUs) are sophisticated systems that combine electric motors and transmissions, operating under demanding thermal conditions.
Race Track Tank Sloshing
- Used Products: shonDy
Fuel-tank sloshing is the oscillation of the free fuel surface in a partially filled tank caused by rapid acceleration, braking, cornering, and curb strikes.
River Debris Management Simulation
- Used Products: shonDy
Rivers transport branches, logs, and man-made debris—especially during floods. When this material jams at bridges, culverts, or intakes, it restricts flow, raises upstream water levels, and accelerates scour and structural damage.
Electric Drive Unit - Part III: Transmission
- Used Products: shonDy
Electric Drive Units (EDUs) are at the heart of modern electric vehicles, combining the electric motor and transmission into a single, compact system.
Electric Drive Unit - Part II: E-Engine
- Used Products: shonDy
Electric Drive Units (EDUs) are at the heart of modern electric vehicles, combining the electric motor and transmission into a single, compact system.
Electric Drive Unit - Part I: Simulating Lubricant Flow in the Rotor
- Used Products: shonDy
Electric Drive Units (EDUs) are at the heart of modern electric vehicles, combining the electric motor and transmission into a single, compact system.
Navigating Puddles with shonDy
This case study demonstrates the capabilities of shonDy and shonMesh in simulating complex automotive scenarios, specifically a car navigating through a channel with speed bumps and water-filled puddles.
Car wading with shonDy
In the context of the automotive industry, wading or fording refers to a car moving through relatively deep water at a low velocity, such as crossing rivers or flooded roads.
Gear box lubrication at low temperature with shonDy
- Used Products: shonDy
Gear lubrication is crucial for maintaining efficient and durable gear systems by reducing friction, dissipating heat, and preventing wear and corrosion.

Engineering Services
Our experienced engineers are ready to help you with your engineering challenges.
We offer a wide range of engineering services in different fields.
- Comprehensive service for electric drive systems, from concept design, simulation, testing, and prototype to connect the virtual and the real world.
- By replacing the physical temperature sensor with a simulation, the temperature field, which cannot be measured by a physical sensor can be obtained. Digital twins are realized through motor prediction models.
- Transparent shell lubrication testing.
