Before: Insufficient simulation capacities to calculate flow resistance
An efficient way of working, continuous improvement and maintaining competitiveness are the guiding principles of the committed aero /carbon team.
“Our main goal in CFD is to generate as much downforce as possible so that the racing car can turn faster. This also increases the overall performance of the vehicle,” explains Kevin Eichner-Lisboa (FaSTTUBe Aero Performance Front Wing, underbody).
After creating a geometry, irrelevant elements that are not directly flowed around are filtered out and the aerodynamic simulation starts immediately. “Each simulation contains only one change. The results are compared with the current baseline. The respective changes are further refined in the following simulations. The baseline is assimilated every 3-4 weeks. Such short development cycles require continuous, fast and complex simulations that assume high computing power.”
This kind of performance was not sufficiently available at an earlier point from now. Before CPU 24/7 had been supporting FaSTTUBe, the engineering students executed calculations on their own laptops. In order to increase their development cycles, FaSTTUBe urgently needed more computing capacity.
After: Reaching benchmarks faster with highly customized HPC resources
“Fortunately CPU 24/7 approached us at the right time. With ready-to-use cloud computing resources, we are now simulating many times faster and much more efficiently.” These HPC resources include four servers with 12 cores each and 48 GB RAM, as well as the corresponding storage space for the simulations. By using permanent remote desktop access to the machines and an adapted queueing system, the students are able to carry out aerodynamic simulations independently. A pre-installed working environment with Ansys Fluent software (students bring their own licenses) as well as competent and fast support, e.g. when setting up new features, saves valuable time for engineering.
Time to develop, improve and finally win the formula student.
Advantages of this solution:
- Permanent access to high-end HPC resources for short simulation runtimes
- Highly customized, ready-to-use working environment with suitable CAE software and queueing system
- First level support from HPC and CAE specialists with short response times
