ACME2014 22nd UK National Conference of the Association for Computational Mechanics in Engineering 2nd - 4th April 2014 College of Engineering, Mathematics and Physical Sciences, University of Exeter, UK Book of Abstracts Edited by: Akbar Javadi Mohammed S. Hussain March 2014 University of Exeter, UK PREFACE The UK Association for Computational Mechanics in Engineering (ACME) was founded with the aim of promoting research in computational mechanics and various engineering applications and establishing formal links and with similar organisations in Europe and the International Association of Computational Mechanics (IACM). One of the principal activities of ACME involves the organisation of the annual conference. The first such conference took place at the University College of Wales Swansea in 1993. Since then, the conferences have provided a forum for reviewing research activities in many areas of mechanics, with an emphasis on interdisciplinary aspects. The conferences have proved to be particularly useful events for bringing together researchers from different disciplines, and especially for providing young researchers with opportunities to present their work. These conference proceedings contain more than 80 short abstracts presented at the 22nd ACME Conference that was held in the Department of Engineering at the University of Exeter from 3rd to 4th April 2014, following the 3rd ACME School on 2nd April, where four lectures were delivered on the topics of Isogeometric Analysis and Automatic Meshing by renowned academics. On behalf of the local organising committee, I would like to thank many people who have contributed to this conference, especially, all the authors who meticulously prepared their papers and presented their original research. I would like to express my gratitude to the three invited keynote speakers, Professor Hywel Thomas, Mr Adrian Gaylard and Professor Bassam Izzuddin for their thought provoking lectures and seminal scholarly contributions.

  • Fenics-HPC: Automated Predictive High-Performance Finite Element
    FEniCS-HPC: Automated predictive high-performance finite element computing with applications in aerodynamics Johan Hoffman1, Johan Jansson2, and Niclas Jansson3 1 Computational Technology Laboratory, School of Computer Science and Communication, KTH, Stockholm, Sweden and BCAM - Basque Center for Applied Mathematics, Bilbao, Spain [email protected] 2 BCAM - Basque Center for Applied Mathematics, Bilbao, Spain and Computational Technology Laboratory, School of Computer Science and Communication, KTH, Stockholm, Sweden [email protected] 3 RIKEN Advanced Institute for Computational Science, Kobe, Japan [email protected] Abstract. Developing multiphysics finite element methods (FEM) and scalable HPC implementations can be very challenging in terms of soft- ware complexity and performance, even more so with the addition of goal-oriented adaptive mesh refinement. To manage the complexity we in this work present general adaptive stabilized methods with automated implementation in the FEniCS-HPC automated open source software framework. This allows taking the weak form of a partial differential equation (PDE) as input in near-mathematical notation and automati- cally generating the low-level implementation source code and auxiliary equations and quantities necessary for the adaptivity. We demonstrate new optimal strong scaling results for the whole adaptive framework applied to turbulent flow on massively parallel architectures down to 25000 vertices per core with ca. 5000 cores with the MPI-based PETSc backend and for assembly down to 500 vertices per core with ca. 20000 cores with the PGAS-based JANPACK backend. As a demonstration of the high impact of the combination of the scalability together with the adaptive methodology allowing prediction of gross quantities in turbulent flow we present an application in aerodynamics of a full DLR-F11 aircraft in connection with the HiLift-PW2 benchmarking workshop with good match to experiments.

  • The DUNE-Fem-DG Framework
    Extendible and Efficient Python Framework for Solving Evolution Equations with Stabilized Discontinuous Galerkin Methods Andreas Dedner, Robert Klofkorn¨ ∗ Abstract This paper discusses a Python interface for the recently published DUNE-FEM- DG module which provides highly efficient implementations of the Discontinuous Galerkin (DG) method for solving a wide range of non linear partial differential equations (PDE). Although the C++ interfaces of DUNE-FEM-DG are highly flexible and customizable, a solid knowledge of C++ is necessary to make use of this powerful tool. With this work easier user interfaces based on Python and the Unified Form Language are provided to open DUNE-FEM-DG for a broader audience. The Python interfaces are demonstrated for both parabolic and first order hyperbolic PDEs. Keywords DUNE,DUNE-FEM, Discontinuous Galerkin, Finite Volume, Python, Advection-Diffusion, Euler, Navier-Stokes MSC (2010): 65M08, 65M60, 35Q31, 35Q90, 68N99 In this paper we introduce a Python layer for the DUNE-FEM-DG1 module [14] which is available open-source. The DUNE-FEM-DG module is based on DUNE [5] and DUNE- FEM [20] in particular and makes use of the infrastructure implemented by DUNE-FEM for seamless integration of parallel-adaptive Finite Element based discretization methods. DUNE-FEM-DG focuses exclusively on Discontinuous Galerkin (DG) methods for var- ious types of problems. The discretizations used in this module are described by two main papers, [17] where we introduced a generic stabilization for convection dominated problems that works on generally unstructured and non-conforming grids and [9] where we introduced a parameter independent DG flux discretization for diffusive operators.

  • Abstractions and Automated Algorithms for Mixed Domain Finite Element Methods
    Abstractions and automated algorithms for mixed domain finite element methods CÉCILE DAVERSIN-CATTY, Simula Research Laboratory, Norway CHRIS N. RICHARDSON, BP Institute, University of Cambridge, United Kingdom ADA J. ELLINGSRUD, Simula Research Laboratory, Norway MARIE E. ROGNES, Simula Research Laboratory, Norway Mixed dimensional partial differential equations (PDEs) are equations coupling unknown fields defined over domains of differing topological dimension. Such equations naturally arise in a wide range of scientific fields including geology, physiology, biology and fracture mechanics. Mixed dimensional PDEs arealso commonly encountered when imposing non-standard conditions over a subspace of lower dimension e.g. through a Lagrange multiplier. In this paper, we present general abstractions and algorithms for finite element discretizations of mixed domain and mixed dimensional PDEs of co-dimension up to one (i.e. nD-mD with jn −mj 6 1). We introduce high level mathematical software abstractions together with lower level algorithms for expressing and efficiently solving such coupled systems. The concepts introduced here have alsobeen implemented in the context of the FEniCS finite element software. We illustrate the new features through a range of examples, including a constrained Poisson problem, a set of Stokes-type flow models and a model for ionic electrodiffusion. CCS Concepts: • Mathematics of computing → Solvers; Partial differential equations; • Computing methodologies → Modeling methodologies. Additional Key Words and Phrases: FEniCS project, mixed dimensional, mixed domains, mixed finite elements 1 INTRODUCTION Mixed dimensional partial differential equations (PDEs) are systems of differential equations coupling solution fields defined over domains of different topological dimensions. Problem settings that call for such equations are in abundance across the natural sciences [27, 47], in multi-physics problems [13, 48], and in mathematics [8, 29].

(hons) Benjamin Rüth Submission Date: September 27, 2019 I confirm that this bachelor’s thesis in engineering science is my own work and I have documented all sources and material used. Munich, September 27, 2019 Richard Hertrich Abstract In partitioned fluid structure interaction, a structure solver and a fluid solver are coupled via boundary conditions at the interface. This thesis presents partitioned FSI simulations using OpenFOAM for the fluid, preCICE as a coupling tool, and a structure solver I developed with the FEM library FEniCS. I extended the preCICE- FEniCS adapter to match the requirements for FSI, such that users can couple FEniCS simulations with vector functions and read conservatively mapped quantities from preCICE to a FEniCS solver. Plus, the adapter now features a mapping between pseudo-3D OpenFOAM and 2D FEniCS. The setup is tested with two FSI scenarios: An elastic flap in a channel and the FSI3 benchmark. I compare the results to validated partitioned FSI methods and reference results in literature to validate the preCICE-FEniCS adapter and the structure solver.

Hierarchical a posteriori error estimation of Bank–Weiser type in the FEniCS Project∗ Raphaël Bulle† Jack S. Hale† Alexei Lozinski‡ Stéphane P. A. Bordas† Franz Chouly§ February 10, 2021 Abstract. In the seminal paper of Bank and Weiser [Math. Comp., 44 (1985), pp. 283–301] a new a posteriori estimator was introduced. This estimator requires the solution of a local Neumann problem on every cell of the finite element mesh. Despite the promise of Bank– Weiser type estimators, namely locality, computational efficiency, and asymptotic sharpness, they have seen little use in practical computational problems. The focus of this contribution is to describe a novel implementation of hierarchical estimators of the Bank–Weiser type in a modern high-level finite element software with automatic code generation capabilities.

    Composite Structures 253 (2020) 112755 Contents lists available at ScienceDirect Composite Structures journal homepage: www.elsevier.com/locate/compstruct A cross-sectional aeroelastic analysis and structural optimization tool for slender composite structures ⇑ Roland Feil a, , Tobias Pflumm b, Pietro Bortolotti a, Marco Morandini c a National Renewable Energy Laboratory, Boulder, Colorado, USA b Technical University of Munich, Germany c Politecnico di Milano, Italy ARTICLE INFO ABSTRACT Keywords: A fully open‐source available framework for the parametric cross‐sectional analysis and design optimization of SONATA slender composite structures, such as helicopter or wind turbine blades, is presented. The framework— VABS Structural Optimization and Aeroelastic Analysis (SONATA)—incorporates two structural solvers, the commer- ANBA4 cial tool VABS, and the novel open‐source code ANBA4. SONATA also parameterizes the design inputs, post- Parametric design framework processes and visualizes the results, and generates the structural inputs to a variety of aeroelastic analysis Composite structures tools. It is linked to the optimization library OpenMDAO. This work presents the methodology and explains the fundamental approaches of SONATA. Structural characteristics were successfully verified for both VABS and ANBA4 using box beam examples from literature, thereby verifying the parametric approach to generating the topology and mesh in a cross section as well as the solver integration. The framework was furthermore exercised by analyzing and evaluating a fully resolved highly flexible wind turbine blade. Computed structural characteristics correlated between VABS and ANBA4, including off‐diagonal terms. Stresses, strains, and defor- mations were recovered from loads derived through coupling with aeroelastic analysis. The framework, there- fore, proves effective in accurately analyzing and optimizing slender composite structures on a high‐fidelity level that is close to a three‐dimensional finite element model.
