“…These interface meshes can be defined both for two-dimensional simulations (oriented in the (x, y) plane and using the cell centers), as well as for three-dimensional simulations. In addition to mesh points, the adapter can also extract mesh edges and construct mesh triangles, an essential component for nearest-projection data mapping (i.e., interpolation on the nearest mesh element of the other participant's mesh) [6].…”

“…preCICE 2 [6,7] is a coupling library designed for minimally-invasive integration into existing codes. The library itself is not related or specific in any way to OpenFOAM and can be used by any simulation code, calling the high-level API of preCICE, which is available for several programming languages currently common in scientific computing (including C++, C, Fortran, Python, Julia, and Matlab).…”

“…Furthermore, the adapter needs to be independent not only of the specific solver, but also of the OpenFOAM version. We support recent and older versions from both OpenCFD as well as the OpenFOAM Foundation with version-specific adapter releases and development branches (including OpenFOAM v2212 and OpenFOAM 10, the latest releases at this time) 6 . We focus on CHT and FSI, but the adapter is extendable for any surface-or volume-coupled application.…”

“…While individual codes have been coupled to OpenFOAM (see section 2), we are interested in codeindependent coupling solutions. One such solution is the coupling library preCICE [6,7]. preCICE is an open-source coupling library, which has proven scalability to tens of thousands of cores [8], comes with many ready-to-use adapters for other simulation codes, and has a fast-growing community of developers and users.…”

Multi-physics simulations, such as conjugate heat transfer or fluid-structure interaction, are often constructed completely in OpenFOAM. However, they can also be formed by coupling OpenFOAM to third-party simulation software via a coupling tool. This approach indirectly adds to the capabilities of OpenFOAM those of other simulation tools (such as physical models or discretization methods more fitting for specific applications), and allows building complex multi-physics simulations by connecting specialized single-physics codes. We present the OpenFOAM-preCICE adapter, a function object that enables standard OpenFOAM solvers to use the open-source, massively parallel coupling library preCICE, without requiring any code modifications. We review alternative coupling approaches, analyze our design decisions, peek into key implementation details, validate the adapter, study the effect on runtime, and give an overview of the growing community of users and contributors.

Dissolution-driven stress corrosion cracking is a complicated multi-physics phenomenon consisting of coupling between mechanical stress and corrosion. In this coupled electro-chemo-mechanical problem, the combined effects of mechanical field, localised corrosion and the microstructure with the effects of grain boundaries are investigated. Therein, corrosion kinetics are accelerated by mechanical straining and also affected by the different material properties along the grain boundaries. A phase-field modelling approach, a method for regularizing sharp interfaces with smooth gradients, is utilized to describe the metal-electrolyte interface during localized metal dissolution. The current contribution presents a partitioned computational framework, as an extension of recently published works for solving pitting corrosion and stress corrosion cracking at the micro-scale. In this extension, mechanically assisted corrosion is coupled bi-directionally and solved on two software instances facilitating simulation at different time scales, using an open-source coupling software. The performance of the proposed computational framework is demonstrated through various deterioration model system situations in 2D.

Wind energy is an essential part of the Green Deal. The trend to increase the size of wind turbines, especially offshore, introduces additional dynamic effects at the long and flexible blades. Embedded in the CRC 1463, DFG, we are working on the fluid-structure interaction to avoid dynamic stall and investigate flutter effects and blade breathing of ultra-slim blades [1,2]. This requires an accurate numerical setup that reliably captures the fluid-structure interactions due to the highly turbulent flow and large deformations of the blades. In preliminary work, the Unsteady Reynolds-averaged Navier-Stokes method (URANS) in openFOAM [3] was used to simulate the flow around rotating helicopter blades with a changing angle of attack.[4] successfully predicted the distinct dynamic stall hysteresis with moderate computational effort and captured extreme values (load peaks) within the experimental uncertainties. This aerodynamic solver is to be coupled with a structural solution, for which deal. II [5] provides the linear elastic blade model. The fluid and the structure solvers are coupled via the software preCICE [6] and solved with a staggered approach. Numerical results are presented for a simplified 2D cross-section of a rectangular solid of carbon-fiber-reinforced polymers and a steady inflow velocity. Key challenges for the coupling of the solvers are discussed and the future work is outlined.
