    Anisotropic mesh adaptation in Firedrake with PETSc DMPlex

    Despite decades of research in this area, mesh adaptation capabilities arestill rarely found in numerical simulation software. We postulate that theprimary reason for this is lack of usability. Integrating mesh adaptation intoexisting software is difficult as non-trivial operators, such as error metricsand interpolation operators, are required, and integrating available adaptiveremeshers is not straightforward. Our approach presented here is to firstintegrate Pragmatic, an anisotropic mesh adaptation library, into DMPlex, aPETSc object that manages unstructured meshes and their interactions withPETSc's solvers and I/O routines. As PETSc is already widely used, this willmake anisotropic mesh adaptation available to a much larger community. As ademonstration of this we describe the integration of anisotropic meshadaptation into Firedrake, an automated Finite Element based system for theportable solution of partial differential equations which already uses PETScsolvers and I/O via DMPlex. We present a proof of concept of this integrationwith a three-dimensional advection test case.

    Compatible finite element methods for numerical weather prediction

    , Proceedings of the EMCWF Annual Seminar

    This article takes the form of a tutorial on the use of a particular class ofmixed finite element methods, which can be thought of as the finite elementextension of the C-grid staggered finite difference method. The class is oftenreferred to as compatible finite elements, mimetic finite elements, discretedifferential forms or finite element exterior calculus. We provide anelementary introduction in the case of the one-dimensional wave equation,before summarising recent results in applications to the rotating shallow waterequations on the sphere, before taking an outlook towards applications inthree-dimensional compressible dynamical cores.

    Design optimisation and resource assessment for tidal-stream renewable energy farms using a new continuous turbine approach

    , Renewable Energy, ISSN: 1879-0682

    This paper presents a new approach for optimising the design of tidal stream turbine farms. In this approach, the turbine farm is represented by a turbine density function that specifies the number of turbines per unit area and an associated continuous locally-enhanced bottom friction field. The farm design question is formulated as a mathematical optimisation problem constrained by the shallow water equations and solved with efficient, gradient-based optimisation methods. The resulting method is accurate, computationally efficient, allows complex installation constraints, and supports different goal quantities such as to maximise power or profit. The outputs of the optimisation are the optimal number of turbines, their location within the farm, the overall farm profit, the farm's power extraction, and the installation cost.We demonstrate the capabilities of the method on a validated numerical model of the Pentland Firth, Scotland. We optimise the design of four tidal farms simultaneously, as well as individually, and study how farms in close proximity may impact upon one another.

    Reconciling biofuels and food security: priorities for action

    , Global Change Biology Bioenergy, ISSN: 1757-1693

    Addressing the challenges of understanding and managing complex interactions among food security, biofuels, and resource management requires a focus on specific contextual problems and opportunities. The United Nations’ 2030 Sustainable Development Goals prioritize food and energy security; bioenergy plays an important role in achieving both goals. Effective food security programs begin by clearly defining the problem and asking, “What can be done to effectively assist people at high risk?” Headlines and cartoons that blame biofuels for food insecurity may reflect good intentions but mislead the public and policy makers because they obscure the main drivers of local food insecurity and ignore opportunities for biofuels to contribute to solutions. Applying sustainability guidelines to bioenergy will help achieve near- and long- term goals to eradicate hunger. Priorities for achieving successful synergies between bioenergy and food security include (1) clarifying communications with clear and consistent terms, (2) recognizing that food and bioenergy need not compete for land and instead, need to be integrated with improved resource management, (3) investing in innovations to build capacity and infrastructure such as rural agricultural extension and technology, (4) promoting stable prices that incentivize local production, (5) adopting flex crops that can provide food along with other products and services to society, and (6) engaging stakeholders in identifying and assessing specific opportunities for biofuels to improve food security. Systematic monitoring and analysis to support adaptive management and continual improvement are essential elements to build synergies and help society equitably meet growing demands for both food and energy.
