Business Impact Summary
Challenge Solution Result
Simpact Engineering, a specialist in CAE and impact analysis, based in Warwick, UK, needed flexible and cost-effective access to a modern HPC cluster in order to meet the demanding timescales of a design project with a major automotive manufacturer. After running a series of LS-DYNA3D benchmark tests on the enCORE service, Simpact selected the service due to the excellent performance of the cluster and its cost-effectiveness. Simpact’s LS-DYNA 3D models delivered optimum performance on 128 CPU cores, and the challenging project timescales were met using the enCORE service in this configuration.


Commercial and technical challenges drive demand for high performance computing

Market forces and strong competition are forcing companies to bring products to market more quickly and to reduce development costs to an absolute minimum. This is particularly evident in advanced engineering, where the demand for greater fidelity within ever more complex computational models is continually growing. The results of this are growing challenges in terms of affordable software and the need to access appropriate compute power required to deliver the desired quality of results within acceptable timescales.
Warwick-based CAE consultancy Simpact are specialists in the computational simulation of impacts, and one of their areas of expertise is automotive safety .

LS DYNAApplications such as LS-DYNA have transformed this aspect of vehicle design, largely removing the extremely costly and time consuming process of physical vehicle impact testing during the design process.
For a recent automotive project, Simpact needed to run complex LS-DYNA simulations using large models consisting of around 10 million elements. To achieve this within acceptable timescales, they required access to a HPC cluster, so they turned to OCF to evaluate the enCORE service.
Tim Williams, joint founder and Director of Simpact said “to date, we have been able to run up to 24CPU of LS-DYNA in our Warwick office. With the use of the enCORE hardware we are now able to run large models in less than half the elapsed time. This has had a significant impact on our product development process”.
Simpact’s CAE engineers found it easy to work with the IT specialists at OCF for the integration of their office based LS-DYNA licence. Customer confidentiality is key for Simpact and they were reassured by the security measures we have in place. Dirk Landheer, joint founder and Director of Simpact, commented, “OCF allowed us to rapidly upscale our CPU capacity. This makes is possible for specialist SMEs such as Simpact to meet the demand from large OEMs where previously this was the domain of only a handful of international companies.”
