High fidelity numerical flow simulations are an important part of development processes in the wind, automotive and aerospace industries. The state of the art for performing complex flow simulations is simulation on high performance computers. Here, GPUs play a dominant role due to their improved computing power compared to CPUs.

The overall goal of the EXASIM project is to enable the efficient use of highly parallel computer hardware and the associated acceleration of the flow simulation code OpenFOAM. This is to be achieved through the coupling of OpenFOAM with the open source library Ginkgo by the SCC. The UCFD will provide a portfolio of test cases, including complex cases from the wind energy sector. The associated partner ENERCON contributes with its expertise and the definition of industrially relevant test cases and the associated partner AWS with access to the AWS cloud platform for extensive scaling tests.

The ISTM subproject aims at implementing performant inflow and outflow boundary conditions for scale-resolving flow simulations. This should lead to a decrease of the required inflow domain length and a reduction of the computational cost. Furthermore, the boundary conditions will be evaluated for their generalizability to complex application scenarios and optimized for the GPU framework Ginkgo.
