The Virtual Element Method for the 3D Resistive Magnetohydrodynamic model

Lourenço Beirão da Veiga, Franco Dassi, Gianmarco Manzini, Lorenzo Mascotto

英文摘要：

We present a four-field Virtual Element discretization for the time-dependent resistive Magnetohydrodynamics equations in three space dimensions, focusing on the semi-discrete formulation. The proposed method employs general polyhedral meshes and guarantees velocity and magnetic fields that are divergence free up to machine precision. We provide a full convergence analysis under suitable regularity assumptions, which is validated by some numerical tests.

Adaptive two- and three-dimensional multiresolution computations of resistive magnetohydrodynamics

Fully adaptive computations of the resistive magnetohydrodynamic (MHD) equations are presented in two and three space dimensions using a finite volume discretization on locally refined dyadic grids. Divergence cleaning is used to control the incompressibility constraint of the magnetic field. For automatic grid adaptation a cell-averaged multiresolution analysis is applied which guarantees the precision of the adaptive computations, while reducing CPU time and memory requirements. Implementation issues of the open source code CARMEN-MHD are discussed. To illustrate its precision and efficiency…

The virtual element method for resistive magnetohydrodynamics

We present a virtual element method (VEM) for the numerical approximation of the electromagnetics subsystem of the resistive magnetohydrodynamics (MHD) model in two spatial dimensions. The major advantages of the virtual element method include great flexibility of polygonal meshes and automatic divergence-free constraint on the magnetic flux field. In this work, we rigorously prove the well-posedness of the method and the solenoidal nature of the discrete magnetic flux field. We also derive stability energy estimates. The design of the method includes three choices for the construction of the …

Exponential Integrators for Resistive Magnetohydrodynamics: Matrix-free Leja Interpolation and Efficient Adaptive Time Stepping

We propose a novel algorithm for the temporal integration of the resistive magnetohydrodynamics (MHD) equations. The approach is based on exponential Rosenbrock schemes in combination with Leja interpolation. It naturally preserves Gauss's law for magnetism and is unencumbered by the stability constraints observed for explicit methods. Remarkable progress has been achieved in designing exponential integrators and computing the required matrix functions efficiently. However, employing them in MHD simulations of realistic physical scenarios requires a matrix-free implementation. We show how an e…

A divergence-free semi-implicit finite volume scheme for ideal, viscous and resistive magnetohydrodynamics

本文提出了一种基于压力的半隐式有限体积求解器，用于求解可压缩的理想、粘性及电阻磁流体动力学（MHD）方程。该方法在多个空间维度中保持质量、动量和总能量的守恒，并通过多维黎曼求解器在适当交错的网格上精确满足磁场的无散度条件，即使在存在电阻效应的情况下。该方法通过双旋度形式处理电阻项，并在动量方程和总能量方程中隐式离散所有与压力相关的项。时间步长仅基于流体速度和阿尔芬波速度，而不基于磁声波速度。该方法特别适用于低马赫数流动和MHD方程的不可压缩极限，其中传统的显式密度基Godunov型有限体积求解器由于CFL条件越来越严格和数值粘性在不可压缩极限下的错误标度而变得越来越低效和不准确。我们展示了在低马赫数范围内相关的MHD测试问题，其中新的半隐式算法比传统显式有限体积方法快50倍，这在计算效率上是一个显著的提升。然而，我们的数值结果证实，该新方法在经典MHD测试案例中也能很好地处理强激波。因此，该新方案是一种真正的所有马赫数流动求解器。

A structure-preserving finite element method for compressible ideal and resistive MHD

We construct a structure-preserving finite element method and time-stepping scheme for compressible barotropic magnetohydrodynamics (MHD) both in the ideal and resistive cases, and in the presence of viscosity. The method is deduced from the geometric variational formulation of the equations. It preserves the balance laws governing the evolution of total energy and magnetic helicity, and preserves mass and the constraint $ \operatorname{div}B = 0$ to machine precision, both at the spatially and temporally discrete levels. In particular, conservation of energy and magnetic helicity hold at the …

A novel structure preserving semi-implicit finite volume method for viscous and resistive magnetohydrodynamics

In this work we introduce a novel semi-implicit structure-preserving finite-volume/finite-difference scheme for the viscous and resistive equations of magnetohydrodynamics (MHD) based on an appropriate 3-split of the governing PDE system, which is decomposed into a first convective subsystem, a second subsystem involving the coupling of the velocity field with the magnetic field and a third subsystem involving the pressure-velocity coupling. The nonlinear convective terms are discretized explicitly, while the remaining two subsystems accounting for the Alfven waves and the magneto-acoustic wav…
