||||
self.simulation_mode = simulation_mode
|
||||
if self.simulation_mode:
|
||||
# 仿真逻辑
|
||||
else:
|
||||
# 真实逻辑
|
||||
|
||||

])
|
||||
|
||||
return error_info
|
||||
```
|
||||
|
||||
## Data Models
|
||||
|
||||
### 1. 真实网格结果模型
|
||||
```python
|
||||
class RealMeshResult:
|
||||
def __init__(self):
|
||||
self.success: bool = False
|
||||
self.element_count: int = 0
|
||||
self.node_count: int = 0
|

```
|
||||
|
||||
## API Changes
|
||||
|
||||
### 1. 移除仿真模式参数
|
||||
```python
|
||||
# 移除前
|
||||
@api_bp.route('/mesh/generate', methods=['POST'])
|
||||
def generate_mesh():
|
||||
simulation_mode = request.json.get('simulation_mode', False)
|
||||
# ...
|
||||
|
||||
# 移除后
|
||||
@api_bp.route('/mesh/generate', methods=['POST'])
|
||||
def generate_mesh():
|
||||
# 直接使用真实模式，无需参数
|
||||
# ...
|
||||
```
|
||||
|
||||
### 2. 新增网格文件API
|
||||
```python
|
||||
@api_bp.route('/mesh/files', methods=['GET'])
|
||||
def get_mesh_files():
|
||||
"""获取生成的网格文件列表"""
|
||||
|
||||
@api_bp.route('/mesh/files/<file_format>', methods=['GET'])
|
||||
def download_mesh_file(file_format):
|
||||
"""下载指定格式的网格文件"""
|
||||
|
||||
@api_bp.route('/mesh/quality/detailed', methods=['GET'])
|
||||
def get_detailed_quality_metrics():
|
||||
"""获取详细的网格质量指标"""
|
||||
```
|
||||
|
||||
## Implementation Strategy
|
||||
|
||||
### 1. 分阶段移除仿真模式
|
||||
1. **第一阶段**: 识别所有simulation_mode相关代码
|
||||
2. **第二阶段**: 逐个模块移除仿真逻辑，保留真实逻辑
|
||||
3. **第三阶段**: 清理相关参数和配置
|
||||
4. **第四阶段**: 更新API文档和测试
|
||||
|
||||
### 2. 增强真实功能

||||
1. **网格文件导出**: 实现多格式网格文件导出
|
||||
2. **质量数据获取**: 从ANSYS获取真实质量指标
|
||||
3. **可视化增强**: 支持质量颜色映射和多视角
|
||||
4. **进度跟踪**: 实现真实的ANSYS操作进度监控
|
||||
|
||||
### 3. 错误处理改进
|
||||
1. **ANSYS错误分类**: 根据错误类型提供具体建议
|
||||
2. **诊断信息收集**: 收集ANSYS环境信息用于故障排除
|
||||
3. **恢复机制**: 实现会话恢复和资源清理
|
||||
|
||||
## Testing Strategy
|
||||
|
||||
### 1. 真实环境测试
|
||||
- **ANSYS集成测试**: 使用真实ANSYS环境测试所有功能
|
||||
- **网格文件验证**: 验证导出的网格文件可以被其他软件读取
|
||||
- **质量数据准确性**: 对比ANSYS GUI中的质量数据
|
||||
|
||||
### 2. 错误场景测试
|
||||
- **ANSYS不可用**: 测试ANSYS未安装或许可证不可用的情况
|
||||
- **内存不足**: 测试大型网格生成时的内存限制
|
||||
- **文件权限**: 测试文件导出权限问题
|
||||
|
||||
### 3. 性能测试
|
||||
- **大型模型**: 测试复杂叶片模型的处理性能
|
||||
- **并发处理**: 测试多个用户同时使用的情况
|
||||
- **长时间运行**: 测试长时间网格生成的稳定性
|
||||
|
||||
## Migration Plan
|
||||
|
||||
### 1. 代码迁移步骤
|
||||
1. 创建新的真实模式专用类
|
||||
2. 逐步替换现有的混合模式类
|
||||
3. 移除所有仿真相关代码
|
||||
4. 更新配置和文档
|
||||
|
||||
### 2. 数据迁移
|
||||
- 无需数据迁移，因为仿真数据不需要保留
|
||||
|
||||
### 3. 部署策略
|
||||
- 蓝绿部署：先部署到测试环境验证，再切换生产环境
|
||||
- 回滚计划：保留当前版本作为备份
|
||||
|
||||
## Security Considerations
|
||||
|
||||
### 1. 文件安全
|
||||
- 网格文件访问权限控制
|
||||
- 临时文件自动清理
|
||||
- 文件路径验证防止目录遍历
|
||||
|
||||
### 2. ANSYS会话安全
|
||||
- 会话隔离确保用户数据不混淆
|
||||
- 自动会话超时和清理
|
||||
- 错误信息过滤避免泄露敏感信息

```python
|
||||
exporter = RealMeshFileExporter(mechanical_session, output_dir="custom/path")
|
||||
```
|
||||
|
||||
## 安全考虑
|
||||
|
||||
### 文件访问控制
|
||||
- 只允许访问导出目录中的文件
|
||||
- 路径验证防止目录遍历攻击
|
||||
- 文件存在性检查
|
||||
|
||||
### 格式验证
|
||||
- 严格的格式白名单
|
||||
- 输入参数验证
|
||||
- 错误信息过滤
|
||||
|
||||
## 性能优化
|
||||
|
||||
### 并发处理
|
||||
- 导出过程不阻塞主网格生成
|
||||
- 异步文件操作
|
||||
- 进度回调支持
|
||||
|
||||
### 文件管理
|
||||
- 自动清理旧文件（可扩展）
|
||||
- 文件大小监控
|
||||
- 磁盘空间检查（可扩展）
|
||||
|
||||
## 已知限制
|
||||
|
||||
### 1. 会话状态管理
|
||||
- 手动导出API（POST /api/mesh/export）需要维护ANSYS会话状态
|
||||
- 当前实现返回501状态，建议使用自动导出功能
|
||||
|
||||
### 2. 文件清理
|
||||
- 暂未实现自动清理旧文件功能
|
||||
- 需要手动管理磁盘空间
|
||||
|
||||
### 3. 并发导出
|
||||
- 当前不支持同时导出多个网格
|
||||
- 需要等待当前导出完成
|
||||
|
||||
## 测试建议
|
||||
|
||||
### 功能测试

||||
1. 测试所有5种格式的导出功能
|
||||
2. 验证导出文件的完整性和可用性
|
||||
3. 测试API端点的响应格式
|
||||
4. 验证文件下载功能
|
||||

||||
```
|
||||
API Routes → Mesh Processor → ANSYSSessionManager
|
||||
↓
|
||||
MeshQualityChecker
|
||||
VisualizationExporter
|
||||
MechdbReader
|
||||
```
|
||||
|
||||
### 2. 移除顺序建议
|
||||
1. **第一步**: 清理ANSYSSessionManager（核心组件）
|
||||
2. **第二步**: 更新依赖组件（MeshQualityChecker, VisualizationExporter等）
|
||||
3. **第三步**: 更新API层（routes.py, mesh_processor.py）
|
||||
4. **第四步**: 更新前端（main.js）
|
||||
5. **第五步**: 清理测试代码
|
||||
|
||||
