Team 166: CFD Study on Flight Aerodynamic
The end-user and CFD expert of this team was again Praveen Bhat, a technology consultant from India INIA, the software Provider was D-adapco with software STAR-CCM+, and the resource provider was NephoScale in California.
This aerodynamics study of an aircraft was performed using CD-adapco’s STAR-CCM+ simulation software on a 40 (virtual) core HPC cloud with Star-CCM+ 9.06 running in the new UberCloud application container. The major aim of this experiment was to demonstrate the dramatic improvements concerning ease of access and use of cloud resources.

The effort for this experiment was 30 hours from the end-user for simulation setup, technical support, reporting and overall management of the project; 2 hours for UberCloud for regular system management to build the Star-CCM+ image, transfer it on to the server, launch the container with the image, monitoring the server etc. Computing resources were used for 600 core-hours in total.

The combination of NephoScale Cloud, UberCloud Containers, and CD-adapco Star-CCM+ helped in speeding up the simulations, completing the project within the stipulated short time frame, and demonstrated the extreme user friendliness of the access and use of the cloud resources.

Team 170: Simulating Car Frontal Impact in the Cloud
The end-user of this team was Stefan Castravete from Caelynx in Romania, software provider was Ulli Göhner from DYNAmore, and resource providers and HPC experts were Thomas Gropp, Alexander Heine, and Christian Unger from CPU 24/7. The model is a full Toyota Yaris Sedan with frontal airbag which is analyzed via Finite Element Method and consists of 1.5 million elements using LS-DYNA.

The effort invested was: for the end user 10 hours simulation setup, technical support, reporting and overall management of the project; UberCloud support 3 hours monitoring & administration of host servers; and 120 core-hours used.

The Cloud resources were a very good fit for performing advanced computational experiments that involve high technical challenges and require high-performance hardware resources to successfully perform the simulation experiments in the cloud.
