CFD and FEA for Automotive and Transportation

The largest automobile manufacturers in the world have adopted 3D simulation as a compulsory step in the product development process. New vehicle designs and automotive components are being verified with simulation, which significantly reduces the number of physical prototypes required for testing and the costs related to their production. Creating a web-based, easy to use, and cost-effective simulation platform, SimScale has made simulation available to small and medium-sized companies as well, to help them keep up with the competition. Removing the large up-front investment into hardware and software licenses as well as the high expertise required by traditional simulation software, SimScale is bringing this unmatched technology to all the companies in the automotive industry, no matter if they are original equipment manufacturers (OEM), tier one, tier two or tier three companies.

Considered the “tool of the future”, computer simulation is providing car manufacturers and all companies involved in the transportation field with other unique advantages, including a shorter design cycle and a minimum time to market. SimScale’s powerful CAE platform includes numerous analysis types for vehicle assemblies, including Solid Mechanics (FEM), Fluid Dynamics (CFD), Thermodynamics, and Acoustics.

The scalable computing capacity offered by SimScale is a valuable tool for supporting, accelerating, and improving product development in the automotive and transportation industry. With SimScale, you can simulate automobiles, motorcycles, bicycles, buses, trains, trucks, helicopters, watercraft, spacecraft, aircraft, or any other vehicle.

Among many others, the components that you can simulate with SimScale are:

• Vehicle bodies (aerodynamics, circulation, turbulent flow, velocity etc.)

• Gear unit and power train (stress calculation, cooling, vibration)

• Chassis (vibration, eigenfrequencies)

• Adjustment rack (stress zones)

• Interior (air conditioning, thermal comfort, airflow, acoustics, temperature distribution)

• Engine compartment (stress analysis, cooling)

• Wheels

Case Study

Carlsson Autotechnik GmbH

Optimize the Aerodynamics of a Vehicle

Since 1984, the Carlsson Autotechnik GmbH has been developing and selling grafting programs for Mercedes-Benz vehicles and providing key engineering services for other vehicle manufacturers including Citroen, Peugeot, Honda, Toyota and SsangYoung. While large automobile companies maintain a large number of development departments with their own test stations for engine, chassis, and body development, Carlsson is facing the challenges of managing the same tasks with limited resources. Using SimScale’s capabilities to simulate the car designs, the company’s mechanical engineers used the resulting data on air drag and downforce as well as pressure, velocity, and turbulence to optimize the aerodynamics of the vehicle.
