MPAS-Ocean Shallow Water Meshes

The MPAS_Ocean_Shallow_Water_Meshes directory contains planar hexagonal mesh files in NetCDF format necessary for running a verification suite of shallow water test cases for the barotropic solver of ocean models using a mimetic finite volume spatial discretization based on the TRiSK scheme. It also contains mesh plots showing the cell centers, edge centers, vertices, and orientation of the normal vectors at the edges; plots of high resolution meshes superimposed on low resolution ones; plots of state variables interpolated from edges and vertices to cell centers along with the interpolation error; plots of state variables interpolated from a high resolution mesh to a low resolution one; and plots of various spatial operators of the TRiSK scheme applied to the state variables along with their error and convergence plots. The associated code can be cloned from the Github repository Rotating_Shallow_Water_Verification_Suite. Please download the MPAS_Ocean_Shallow_Water_Meshes.zip file, unzip it, and place the resulting directory within the meshes directory of Rotating_Shallow_Water_Verification_Suite.

MPAS_Ocean_Shallow_Water_Meshes 目录包含 NetCDF 格式的平面六边形网格文件，这些文件是运行基于 TRiSK 格式（TRiSK scheme）的保形有限体积空间离散格式的海洋模式正压求解器浅水试验算例验证套件所必需的。该目录还涵盖各类配套绘图：包括展示网格单元中心、边中心、顶点及边处法向量方向的网格绘图；高分辨率网格与低分辨率网格叠加对比的绘图；将边与顶点处的状态变量插值至单元中心的绘图及对应插值误差绘图；将高分辨率网格处的状态变量插值至低分辨率网格的绘图；以及将 TRiSK 格式的各类空间算子应用于状态变量的绘图，附带其误差与收敛性分析绘图。相关代码可从 GitHub 仓库 Rotating_Shallow_Water_Verification_Suite 克隆获取。请下载 MPAS_Ocean_Shallow_Water_Meshes.zip 文件，解压后将生成的目录放置于 Rotating_Shallow_Water_Verification_Suite 的 meshes 目录下。
