@ -21,3 +21,10 @@ To run the program, simply execute the binary:
## Usage
The load files are in `sim-test/rigid-test/*/json`, generated by `sim-test/rigid-test/*/*.json.in`.
---
## Detailed steps
1. 点击加载文件,选择.json配置文件(选择错误后缀会有提醒).
2. 设置边界条件和材料,点击开始计算.
3. 查看仿真结果,并可选择导出.
4. 可选择结果对比(需要预先准备文件),选择对应例子的`/ref_res`文件夹(错误文件夹名会有提醒),显示对比结果.
