There are many interesting and complex problems which can’t be solved with high fidelity by mechanics or design approaches. Additionally, while physical testing can produce high fidelity data, it can be cost prohibitive. PEC’s advanced computational modeling and simulation expertise can fill this gap as a cost effective and invaluable tool for high fidelity solutions. We are able to apply our computational modeling capabilities to a diverse range of applications.
PEC high fidelity analysis includes static and dynamic structural response and blast and impact load and response prediction with finite element (FE) and computational fluid dynamics (CFD) calculations. Our mechanical and structural analysis capabilities range from structural codes such as SAP to FE codes such as LS-DYNA and to hydrocodes such as CTH for simulating large deformation behavior of structures subjected to shock, impact, or other dynamic loading events.
Sample applications include progressive collapse prediction, blast and fragment loading and blast response, vehicle and missile impact loading and response, debris and fragmentation prediction, explosively driven threats, injury, energy absorbing barriers and safety systems, software enhancements, and acoustics analysis. Employing a computational modeling analysis approach can provide the ability to look at many variations of a potential solution in an economical manner, resulting in a more robust solution.
Our computational hardware resources range from in-house multi-core HPCs to commercial and government HPC platforms. Our in-house capability allows precise control during simulation development and ensures confidentiality of input and results. We can batch execute problems requiring hundreds of processors on the commercial and government resources.
