|
||||
## 实现细节
|
||||
|
||||
### 数据结构
|
||||
|
||||
#### 网格节点 (Node)
|
||||
```cpp
|
||||
struct Node {
|
||||
int id; // 节点ID
|
||||
double x, y, z; // 节点坐标
|
||||
array<int> elems; // 相邻单元列表
|
||||
};
|
||||
```
|
||||
|
||||
#### 网格单元 (Element)
|
||||
```cpp
|
||||
struct Element {
|
||||
int id; // 单元ID
|
||||
array<Node*> vertices; // 顶点列表
|
||||
array<Element*> neighbors; // 相邻单元
|
||||
};
|
||||
```
|
||||
|
||||
#### 数据管理 (MeshData)
|
||||
```cpp
|
||||
class MeshData {
|
||||
string name; // 数据名称
|
||||
DataType type; // 数据类型
|
||||
array<double> values; // 数据值
|
||||
bool output_enabled; // 输出控制
|
||||
};
|
||||
```
|
||||
|
||||
### 核心功能实现
|
||||
|
||||
#### 网格生成
|
||||
- 规则网格：基于给定维度和间距生成
|
||||
- 非规则网格：支持从外部文件导入或程序化生成
|
||||
- 球面网格：基于经纬度和径向参数生成
|
||||
|
||||
#### 数据操作
|
||||
- 插值：支持线性插值和高阶插值
|
||||
- 梯度计算：支持一阶和二阶导数
|
||||
- 数据过滤：支持平滑和降噪操作
|
||||
|
||||
#### 文件格式支持
|
||||
- Gmsh格式：`.msh`文件，支持网格和数据的导入导出
|
||||
- NetCDF格式：`.nc`文件，支持结构化数据的存储
|
||||
- 二进制格式：`.bin`文件，用于高效的数据存储和读取
|
||||
|
||||
### 性能优化
|
||||
|
||||
#### 数据结构优化
|
||||
- 使用连续内存存储提高访问效率
|
||||
- 采用邻接表存储拓扑关系
|
||||
- 使用哈希表加速查找操作
|
||||
|
||||
#### 算法优化
|
||||
- 网格生成采用增量构建策略
|
||||
- 查找操作使用空间分区技术
|
||||
- 并行计算支持（可选）

# GCTL Linear Mesh 2D 文档
|
||||
|
||||
## 简介
|
||||
|
||||
`linear_mesh_2d.h` 定义了GCTL网格库中的二维线性网格类 `linear_mesh_2d`，用于创建和管理二维非结构化线性网格。该类支持不规则分布的网格点，适用于复杂几何形状的离散化。
|
||||
|
||||
## 类继承
|
||||
|
||||
`linear_mesh_2d` 继承自 `base_mesh` 基类，实现了所有虚函数，并添加了二维线性网格特有的功能。
|
||||
|
||||
## 主要API
|
||||
|
||||
### 初始化
|
||||
```cpp
|
||||
// 初始化二维线性网格
|
||||
void init(std::string name, // 网格名称
|
||||
std::string info, // 网格信息
|
||||
const array<point2dc> &nodes, // 节点坐标数组
|
||||
const array<int2> &elements); // 单元连接关系数组
|
||||
```
|
||||
|
||||
### 网格信息
|
||||
```cpp
|
||||
// 获取节点坐标
|
||||
void get_node_coord(int node_idx, // 节点索引
|
||||
double &x, double &y) const;
|
||||
|
||||
// 获取单元节点索引
|
||||
void get_elem_nodes(int elem_idx, // 单元索引
|
||||
int &n1, int &n2) const;
|
||||
|
||||
// 获取单元中心坐标
|
||||
void get_elem_center(int elem_idx, // 单元索引
|
||||
double &x, double &y) const;
|
||||
|
||||
// 获取单元长度
|
||||
double get_elem_length(int elem_idx) const;
|
||||
```
|
||||
|
||||
### 网格查询
|
||||
```cpp
|
||||
// 查找包含指定点的单元
|
||||
bool find_element(double x, double y, // 目标点坐标
|
||||
int &elem_idx) const; // 返回单元索引
|
||||
|
||||
// 获取节点相邻的单元
|
||||
array<int> get_node_elements(int node_idx) const;
|
||||
|
||||
// 获取单元相邻的单元
|
||||
array<int> get_elem_neighbors(int elem_idx) const;
|
||||
```
|
||||
|
||||
### 文件操作
|
||||
```cpp
|
||||
// 保存为Gmsh格式
|
||||
virtual void save_gmsh(std::string filename,
|
||||
index_packed_e packed = Packed) override;
|
||||
|
||||
// 保存为二进制格式
|
||||
virtual void save_binary(std::string filename) override;
|
||||
|
||||
// 读取二进制格式
|
||||
virtual void load_binary(std::string filename) override;
|
||||
```
|
||||
|
||||
## 使用示例
|
||||
|
||||
```cpp
|
||||
// 创建节点坐标数组
|
||||
array<point2dc> nodes;
|
||||
nodes.push_back(point2dc(0.0, 0.0));
|
||||
nodes.push_back(point2dc(1.0, 0.0));
|
||||
nodes.push_back(point2dc(1.0, 1.0));
|
||||
nodes.push_back(point2dc(0.0, 1.0));
|
||||
|
||||
// 创建单元连接关系
|
||||
array<int2> elements;
|
||||
elements.push_back(int2(0, 1)); // 第一条边
|
||||
elements.push_back(int2(1, 2)); // 第二条边
|
||||
elements.push_back(int2(2, 3)); // 第三条边
|
||||
elements.push_back(int2(3, 0)); // 第四条边
|
||||
|
||||
// 创建线性网格
|
||||
gctl::linear_mesh_2d mesh2d;
|
||||
mesh2d.init("boundary", "2D boundary mesh", nodes, elements);
|
||||
|
||||
// 获取单元信息
|
||||
double length = mesh2d.get_elem_length(0); // 获取第一条边的长度
|
||||
|
||||
// 查找包含特定点的单元
|
||||
int elem_idx;
|
||||
if (mesh2d.find_element(0.5, 0.5, elem_idx)) {
|
||||
// 找到包含点(0.5,0.5)的单元
|
||||
}
|
||||
|
||||
// 添加数据并保存
|
||||
mesh2d.add_data(gctl::NodeData, gctl::Scalar, "displacement", 0.0);
|
||||
mesh2d.save_gmsh("boundary.msh", gctl::Packed);
|
||||
```
|
||||
|
||||
## 注意事项
|
||||
|
||||
1. 线性网格主要用于表示一维结构（如边界）在二维空间中的分布
|
||||
2. 每个单元由两个节点定义，表示一条线段
|
||||
3. 节点和单元的编号从0开始
|
||||
4. 支持不规则分布的节点，适合复杂几何形状
|
||||
5. 提供了网格拓扑关系查询功能（节点相邻单元、单元相邻单元等）
|
||||
6. 支持Gmsh和二进制格式的文件操作
|
||||
7. 适用于边界元素法、有限元法等数值计算

// 载入二进制文件
|
||||
void load_binary(std::ifstream &infile);
|
||||
|
||||
// 保存二进制文件
|
||||
void save_binary(std::ofstream &outfile);
|
||||
```
|
||||
|
||||
## 使用示例
|
||||
|
||||
```cpp
|
||||
// 创建数据对象
|
||||
gctl::meshdata data(gctl::NodeData, // 节点数据
|
||||
gctl::Scalar, // 标量类型
|
||||
100, // 数据大小
|
||||
"temperature", // 数据名称
|
||||
true); // 可输出
|
||||
|
||||
// 显示数据信息
|
||||
data.show_info();
|
||||
|
||||
// 显示数据统计信息
|
||||
data.show_stats();
|
||||
|
||||
// 导出矢量数据
|
||||
if (data.valtype_ == gctl::Vector) {
|
||||
array<point3dc> vectors = data.export_vector();
|
||||
}
|
||||
|
||||
// 导出张量数据
|
||||
if (data.valtype_ == gctl::Tensor) {
|
||||
array<tensor> tensors = data.export_tensor();
|
||||
}
|
||||
```
|
||||
|
||||
## 注意事项
|
||||
|
||||
1. 数据对象支持三种类型：标量、矢量和张量
|
||||
2. 数据可以定义在网格的顶点或元素上
|
||||
3. 数据导出时会根据数据类型自动转换为对应的格式
|
||||
4. 二进制文件操作通常由网格类调用，不建议直接使用

# GCTL Regular Grid 文档
|
||||
|
||||
## 简介
|
||||
|
||||
`regular_grid.h` 定义了GCTL网格库中的规则网格类 `regular_grid`，用于创建和管理规则网格。规则网格是最基本的网格类型，具有规则的网格点分布和单元结构。
|
||||
|
||||
## 类继承
|
||||
|
||||
`regular_grid` 继承自 `base_mesh` 基类，实现了所有虚函数，并添加了规则网格特有的功能。
|
||||
|
||||
## 主要API
|
||||
|
||||
### 初始化
|
||||
```cpp
|
||||
// 初始化二维规则网格
|
||||
void init(std::string name, // 网格名称
|
||||
std::string info, // 网格信息
|
||||
int nx, int ny, // x和y方向的网格数
|
||||
double x0, double y0, // 起始点坐标
|
||||
double x1, double y1); // 终止点坐标
|
||||
|
||||
// 初始化三维规则网格
|
||||
void init(std::string name, // 网格名称
|
||||
std::string info, // 网格信息
|
||||
int nx, int ny, int nz, // x、y和z方向的网格数
|
||||
double x0, double y0, double z0, // 起始点坐标
|
||||
double x1, double y1, double z1); // 终止点坐标
|
||||
```
|
||||
|
||||
### 网格信息
|
||||
```cpp
|
||||
// 获取网格维度
|
||||
int get_dimension() const;
|
||||
|
||||
// 获取网格点数
|
||||
void get_grid_num(int &nx, int &ny) const; // 2D
|
||||
void get_grid_num(int &nx, int &ny, int &nz) const; // 3D
|
||||
|
||||
// 获取网格范围
|
||||
void get_grid_range(double &x0, double &y0, // 2D起点
|
||||
double &x1, double &y1) const; // 2D终点
|
||||
void get_grid_range(double &x0, double &y0, double &z0, // 3D起点
|
||||
double &x1, double &y1, double &z1) const; // 3D终点
|
||||
```
|
||||
|
||||
### 网格操作
|
||||
```cpp
|
||||
// 获取指定位置的网格点坐标
|
||||
void get_node_coord(int i, int j, // 2D索引
|
||||
double &x, double &y) const;
|
||||
void get_node_coord(int i, int j, int k, // 3D索引
|
||||
double &x, double &y, double &z) const;
|
||||
|
||||
// 获取指定位置的单元中心坐标
|
||||
void get_elem_center(int i, int j, // 2D索引
|
||||
double &x, double &y) const;
|
||||
void get_elem_center(int i, int j, int k, // 3D索引
|
||||
double &x, double &y, double &z) const;
|
||||
```
|
||||
|
||||
### 文件操作
|
||||
```cpp
|
||||
// 保存为Gmsh格式

|
||||
|
||||
// 保存为二进制格式
|
||||
virtual void save_binary(std::string filename) override;
|
||||
|
||||
// 读取二进制格式
|
||||
virtual void load_binary(std::string filename) override;
|
||||
|
||||
// NetCDF格式操作
|
||||
void load_netcdf_grid(std::string filename,
|
||||
mesh_data_type_e loctype,
|
||||
std::string xname,
|
||||
std::string yname);
|
||||
|
||||
void save_netcdf_grid(std::string filename,
|
||||
std::string title = "untitled");
|
||||
```
|
||||
|
||||
## 使用示例
|
||||
|
||||
```cpp
|
||||
// 创建2D规则网格
|
||||
gctl::regular_grid grid2d;
|
||||
grid2d.init("grid2d", "2D regular grid",
|
||||
100, 100, // 100x100网格
|
||||
0.0, 0.0, // 起点(0,0)
|
||||
1.0, 1.0); // 终点(1,1)
|
||||
|
||||
// 创建3D规则网格
|
||||
gctl::regular_grid grid3d;
|
||||
grid3d.init("grid3d", "3D regular grid",
|
||||
50, 50, 50, // 50x50x50网格
|
||||
0.0, 0.0, 0.0, // 起点(0,0,0)
|
||||
1.0, 1.0, 1.0); // 终点(1,1,1)
|
||||
|
||||
// 获取网格信息
|
||||
int nx, ny, nz;
|
||||
grid3d.get_grid_num(nx, ny, nz);
|
||||
|
||||
// 添加数据并保存
|
||||
grid3d.add_data(gctl::NodeData, gctl::Scalar, "temperature", 25.0);
|
||||
grid3d.save_gmsh("output.msh", gctl::Packed);
|
||||
```
|
||||
|
||||
## 注意事项
|
||||
|
||||
1. 规则网格支持2D和3D两种维度
|
||||
2. 网格点和单元的编号是规则的，可以通过索引直接访问
|
||||
3. 支持多种文件格式的导入导出（Gmsh、二进制、NetCDF）
|
||||
4. 网格范围由起点和终点坐标定义，网格间距自动计算

|
||||
// 获取特定位置的坐标（笛卡尔坐标）
|
||||
double x, y, z;
|
||||
mesh_sph.get_node_coord(90, 180, 0, x, y, z);
|
||||
|
||||
// 添加数据并保存
|
||||
mesh_sph.add_data(gctl::NodeData, gctl::Scalar, "temperature", 0.0);
|
||||
mesh_sph.save_gmsh("earth_model.msh", gctl::Packed);
|
||||
```
|
||||
|
||||
## 注意事项
|
||||
|
||||
1. 坐标系采用地理坐标系约定：
|
||||
- 纬度范围：-90度（南极）到90度（北极）
|
||||
- 经度范围：-180度到180度
|
||||
- 半径：从地心开始计算
|
||||
2. 提供了球面坐标和笛卡尔坐标的双重表示
|
||||
3. 网格在极点附近可能出现变形，需要特别处理
|
||||
4. 经度方向是周期性的，可以处理跨越180度经线的情况
|
||||
5. 支持Gmsh和二进制格式的文件操作
|
||||
6. 适用于地球物理建模、大气科学等领域

# GCTL Tetrahedral Mesh 文档
|
||||
|
||||
## 简介
|
||||
|
||||
`tet_mesh.h` 定义了GCTL网格库中的四面体网格类 `tet_mesh`，用于创建和管理三维空间中的非结构化四面体网格。该类特别适用于复杂三维区域的离散化，支持任意形状的体积域。
|
||||
|
||||
## 类继承
|
||||
|
||||
`tet_mesh` 继承自 `base_mesh` 基类，实现了所有虚函数，并添加了四面体网格特有的功能。
|
||||
|
||||
## 主要API
|
||||
|
||||
### 初始化
|
||||
```cpp
|
||||
// 初始化四面体网格
|
||||
void init(std::string name, // 网格名称
|
||||
std::string info, // 网格信息
|
||||
const array<point3dc> &nodes, // 节点坐标数组
|
||||
const array<int4> &elements); // 单元连接关系数组
|
||||
```
|
||||
|
||||
### 网格信息
|
||||
```cpp
|
||||
// 获取节点坐标
|
||||
void get_node_coord(int node_idx, // 节点索引
|
||||
double &x, double &y, double &z) const;
|
||||
|
||||
// 获取单元节点索引
|
||||
void get_elem_nodes(int elem_idx, // 单元索引
|
||||
int &n1, int &n2, int &n3, int &n4) const;
|
||||
|
||||
// 获取单元中心坐标
|
||||
void get_elem_center(int elem_idx, // 单元索引
|
||||
double &x, double &y, double &z) const;
|
||||
|
||||
// 获取单元体积
|
||||
double get_elem_volume(int elem_idx) const;
|
||||
|
||||
// 获取单元外接球信息
|
||||
void get_elem_circumsphere(int elem_idx, // 单元索引
|
||||
double &x, double &y, double &z, // 球心坐标
|
||||
double &radius) const; // 半径
|
||||
```
|
||||
|
||||
### 网格查询
|
||||
```cpp
|
||||
// 查找包含指定点的单元
|
||||
bool find_element(double x, double y, double z, // 目标点坐标
|
||||
int &elem_idx) const; // 返回单元索引
|
||||
|
||||
// 获取节点相邻的单元
|
||||
array<int> get_node_elements(int node_idx) const;
|
||||
|
||||
// 获取单元相邻的单元
|
||||
array<int> get_elem_neighbors(int elem_idx) const;
|
||||
|
||||
// 获取边界面
|
||||
array<int3> get_boundary_faces() const;
|
||||
```
|
||||
|
||||
### 网格质量评估
|
||||
```cpp
|
||||
// 获取单元质量参数
|
||||
double get_elem_quality(int elem_idx) const;
|
||||
|
||||
// 获取最小二面角
|
||||
double get_elem_min_dihedral_angle(int elem_idx) const;
|
||||
|
||||
// 获取最大二面角
|
||||
double get_elem_max_dihedral_angle(int elem_idx) const;
|
||||
|
||||
// 获取纵横比
|
||||
double get_elem_aspect_ratio(int elem_idx) const;
|
||||
```
|
||||
|
||||
### 文件操作
|
||||
```cpp
|
||||
// 保存为Gmsh格式
|
||||
virtual void save_gmsh(std::string filename,
|
||||
index_packed_e packed = Packed) override;
|
||||
|
||||
// 保存为二进制格式
|
||||
virtual void save_binary(std::string filename) override;
|
||||
|
||||
// 读取二进制格式
|
||||
virtual void load_binary(std::string filename) override;
|
||||
```
|
||||
|
||||
## 使用示例
|
||||
|
||||
```cpp
|
||||
// 创建节点坐标数组
|
||||
array<point3dc> nodes;
|
||||
nodes.push_back(point3dc(0.0, 0.0, 0.0)); // 底面三角形的顶点
|
||||
nodes.push_back(point3dc(1.0, 0.0, 0.0));
|
||||
nodes.push_back(point3dc(0.0, 1.0, 0.0));
|
||||
nodes.push_back(point3dc(0.0, 0.0, 1.0)); // 顶点
|
||||
|
||||
// 创建单元连接关系
|
||||
array<int4> elements;
|
||||
elements.push_back(int4(0, 1, 2, 3)); // 一个四面体
|
||||
|
||||
// 创建四面体网格
|
||||
gctl::tet_mesh mesh;
|
||||
mesh.init("volume", "3D tetrahedral mesh", nodes, elements);
|
||||
|
||||
// 获取单元信息
|
||||
double volume = mesh.get_elem_volume(0); // 获取四面体的体积
|
||||
double quality = mesh.get_elem_quality(0); // 获取四面体的质量参数
|
||||
|
||||
// 获取外接球信息
|
||||
double cx, cy, cz, radius;
|
||||
mesh.get_elem_circumsphere(0, cx, cy, cz, radius);
|
||||
|
||||
// 查找包含特定点的单元
|
||||
int elem_idx;
|
||||
if (mesh.find_element(0.25, 0.25, 0.25, elem_idx)) {
|
||||
// 找到包含点(0.25,0.25,0.25)的四面体
|
||||
}
|
||||
|
||||
// 获取边界
|
||||
array<int3> boundary = mesh.get_boundary_faces();
|
||||
|
||||
// 添加数据并保存
|
||||
mesh.add_data(gctl::NodeData, gctl::Vector, "displacement",
|
||||
array<point3dc>(nodes.size(), point3dc(0,0,0)));
|
||||
mesh.save_gmsh("volume.msh", gctl::Packed);
|
||||
```
|
||||
|
||||
## 注意事项
|
||||
|
||||
1. 四面体网格适用于三维区域的离散化
|
||||
2. 每个单元由四个节点定义，遵循右手法则定义方向
|
||||
3. 节点和单元的编号从0开始
|
||||
4. 提供了完整的网格质量评估功能：
|
||||
- 体积
|
||||
- 二面角
|
||||
- 纵横比
|
||||
- 质量参数
|
||||
5. 支持复杂的拓扑关系查询
|
||||
6. 可以自动识别和提取边界面
|
||||
7. 支持Gmsh和二进制格式的文件操作
|
||||
8. 适用于：
|
||||
- 有限元分析
|
||||
- 计算流体动力学
|
||||
