|
||
|
||
### 🚀 演示流程
|
||
|
||
#### 步骤1：文件上传
|
||
1. 打开演示网页界面
|
||
2. 点击上传区域或拖拽文件
|
||
3. 选择演示文件（推荐从simple_blade.step开始）
|
||
4. 等待文件验证完成
|
||
|
||
#### 步骤2：网格生成
|
||
1. 文件上传成功后，点击"开始生成"按钮
|
||
2. 观察实时进度显示和处理日志
|
||
3. 系统将自动完成以下步骤：
|
||
- 几何导入和验证
|
||
- 自动识别关键区域
|
||
- 应用网格控制
|
||
- 生成网格
|
||
- 质量检查
|
||
|
||
#### 步骤3：结果查看
|
||
1. 查看网格统计信息
|
||
2. 查看质量评估报告
|
||
3. 查看可视化结果（如果可用）
|
||
4. 下载结果文件
|
||
|
||
### 🔧 演示模式说明
|
||
|
||
- **完整模式**：如果安装了ANSYS Mechanical，将使用真实的网格生成功能
|
||
- **演示模式**：如果未安装ANSYS，将使用模拟数据展示完整流程
|

### 🔍 故障排除
|
||
|
||
#### 常见问题
|
||
|
||
1. **文件上传失败**
|
||
- 确认文件格式为.step或.stp
|
||
- 确认文件大小不超过100MB
|
||
- 检查文件是否损坏
|
||
|
||
2. **网格生成失败**
|
||
- 检查几何文件完整性
|
||
- 查看错误日志信息
|
||
- 尝试使用测试几何文件
|
||
|
||
3. **界面无响应**
|
||
- 刷新浏览器页面
|
||
- 检查网络连接
|
||
- 查看浏览器控制台错误
|
||
|
||
#### 技术支持
|
||
|
||
如遇到问题，请：
|
||
1. 查看浏览器控制台错误信息
|
||
2. 查看应用日志文件
|
||
3. 尝试重启演示系统
|
||
|
||
### 📈 性能优化建议
