“…The simulations showed that, given an efficient realization of inter-code communication, scalability and efficiency losses due to the domain splitting are low. The coupled simulation inherits the high scalability and efficiency of the coupled simulation codes [3]. 1 With 2), we can prove that only a very moderate number of outer iterations is required for real-world problems.…”

“…Maintainability & Portability. The high number of commercial and academic codes (2 commercial, 13 academic codes, [3]) that have been coupled with preCICE in the last 5 years based on the work of only a handful of doctoral students hints at an enormous reduction of development time compared to writing a new code from scratch. In addition, the resulting flexibility in exchanging coupled codes allows us to use single-physics solvers optimized for the respective target architectures.…”

Abstract-Large-scale simulations play a central role in science and the industry. Several challenges occur when building simulation software, because simulations require complex software developed in a dynamic construction process. That is why simulation software engineering (SSE) is emerging lately as a research focus. The dichotomous trade-off between scalability and efficiency (SE) on the one hand and maintainability and portability (MP) on the other hand is one of the core challenges. We report on the SE/MP trade-off in the context of an ongoing systematic literature review (SLR). After characterizing the issue of the SE/MP trade-off using two examples from our own research, we (1) review the 33 identified articles that assess the trade-off, (2) summarize the proposed solutions for the tradeoff, and (3) discuss the findings for SSE and future work. Overall, we see evidence for the SE/MP trade-off and first solution approaches. However, a strong empirical foundation has yet to be established; general quantitative metrics and methods supporting software developers in addressing the trade-off have to be developed. We foresee considerable future work in SSE across scientific communities.

“…First steps towards such a feature within the Dune framework have been undertaken with the dune-grid-glue module [50]. Efficient load balancing in complicated multi-domain, or mixed-dimensional setups is challenging and is an active field of research targeted by codes such as the MOOSE framework [32], or preCICE [79]. DuMu x currently supports forward and backward Euler time discretizations only.…”

“…Pore-network models for single-and multi-phase flow will be included into the DuMu x framework in an upcoming release, including static and dynamic approaches. In collaboration with the development team of preCICE [79], the model coupling capabilities of DuMu x with internal and external modules will be further improved. The usability and archivability of DuMu x will be further improved within the aforementioned project SusI which constitutes a step towards reproducible research.…”

We present version 3 of the open-source simulator for flow and transport processes in porous media DuMu x . DuMu x is based on the modular C++ framework Dune (Distributed and Unified Numerics Environment) and is developed as a research code with a focus on modularity and reusability. We describe recent efforts in improving the transparency and efficiency of the development process and community-building, as well as efforts towards quality assurance and reproducible research. In addition to a major redesign of many simulation components in order to facilitate setting up complex simulations in DuMu x , version 3 introduces a more consistent abstraction of finite volume schemes. Finally, the new framework for multi-domain simulations is described, and three numerical examples demonstrate its flexibility.

Abstract:We present an Anderson acceleration-based approach to spatially couple three-dimensional Lattice Boltzmann and Navier-Stokes (LBNS) flow simulations. This allows to locally exploit the computational features of both fluid flow solver approaches to the fullest extent and yields enhanced control to match the LB and NS degrees of freedom within the LBNS overlap layer. Designed for parallel Schwarz coupling, the Anderson acceleration allows for the simultaneous execution of both Lattice Boltzmann and Navier-Stokes solver. We detail our coupling methodology, validate it, and study convergence and accuracy of the Anderson accelerated coupling, considering three steady-state scenarios: plane channel flow, flow around a sphere and channel flow across a porous structure. We find that the Anderson accelerated coupling yields a speed-up (in terms of iteration steps) of up to 40% in the considered scenarios, compared to strictly sequential Schwarz coupling.
