With the SimScale Free Community Plan you have a access to all of the features of SimScale, you will just not be able to create private projects. As with all aerodynamic parts, the undertray had to prove its worth in terms of performance before getting installed on the actual car. Due to its very small frontal area and the ground proximity, the undertray generates downforce without generating much drag.Because of cost and manufacturing reasons, we decided at an early stage of the season that the undertray will have one cambered main tunnel under the monocoque and straight side plates. simscale. The flow under the side plate is accelerated, while the pressure on top of the plate is increased. Simscape Introduction (Chapter 1) of the Physical Modeling Online Training for Formula Student Teams. If the CAD model contains small features, fillets or round faces, which are unlikely to have an impact on the result, it is recommended to remove those details before importing the model into SimScale. Today. SimScale provides cloud-based engineering simulation software for university teams participating in Formula Student UK. Leave the properties as default: The physical situation simulated is a straight line movement with 15 \(m \over s\).
