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，此类文件是运行海洋模型正压求解器的浅水试验算例验证套件所必需的，该求解器采用基于TRiSK格式（TRiSK scheme）的保形有限体积空间离散方法（mimetic finite volume spatial discretization）。本目录还涵盖各类网格可视化绘图：包括展示网格单元中心、边中心、顶点及各边法向量朝向的绘图；高分辨率网格与低分辨率网格叠加对比的绘图；将状态变量从边和顶点插值至单元中心的绘图及对应插值误差图；将状态变量从高分辨率网格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作用于状态变量的绘图，同时附带对应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压缩包，解压后将生成的目录放置于Rotating_Shallow_Water_Verification_Suite的meshes目录下。
