The Galway energy-efficient car (better known as the Geec) is a battery-electric eco-car designed and built by engineering students from National University of Ireland Galway to complete in the Shell Eco-marathon Europe. The team uses ANSYS CFD to minimize aerodynamic drag, which accounts for about one-third of all energy consumption in a highly optimized car. Students leverage ANSYS Mechanical to support lightweighting the design of various components. To develop their next-generation car with a monocoque design, students count on ANSYS Mechanical and ANSYS PrepPost within the ANSYS Workbench platform to determine where additional material would be needed, and where wall thickness can be minimized to save weight. The NUI Galway team expects to reduce the car’s weight by about 10–15 kg as it attempts to match the best cars in the competition.

The Geec is supported by CADFEM UK & Ireland. Information courtesy Nathan Quinlan, Maeve Duffy, Rory Monaghan, Sean Scally and Mike Walsh.
