| Abstract(in English) | Computational Fluid Dynamics (CFD) is taken notice as a design tool for aircraft components. CFD often lacks versatility since reserachers have developed CFD solvers mostly for their own environments. In Addition, CFD takes several days or weeks to run a simulation since it requires huge number of floating-point calculations. UPACS is a common CFD package which has been developed by JAXA since 1998. It supports many solvers and users can run simulation by selecting desired solvers. However UPACS is a convinient tool, it has low efficiency of parallel execution because of it's large degree of versatility. Then, our study aims to implement UPACS accelerator "FLOPS-2D" using multiple FPGAs. In this study, the selectivity is concentrated. Thus, CMUSCL and all flux limiter functions in CMUSCL and TMUSCL was implemented. As a result, at least 24 times higher performance is achieved compared with Core 2 Duo processor at 2.4GHz. Furthermore Simulation generater to select a desired flux limiter function is also implemented. |
