Description of Files

- fe_tools.jl
Includes the module for handling the phase field model.

- helper_funcs.jl
Contains helper functions for solving the Finite Element (FE) problem.

- solver.jl
Contains the main solver.

- mesh_files
Directory containing the meshes of the models.

- AD4SM
Directory containing the package for handling automatic differentiation and element generation.
To add this package via Julia's package manager, run:
```
]add AD4SM
```
or
```
]add https://github.com/avigliotti/AD4SM.jl
```

- qs_cm_hex1x1x1nL20_r500L1100lc0125lcf0500AT1nhl0500*.jl
Sample scripts to launch simulations for specified boundary conditions and models.

Solver Expectations

1. Mesh Directory:
The solver expects to find the mesh files in the directory named `mesh_files`. This can be changed by passing the relevant parameter to the solver.

2. Output Directories:
- JLD2 Files: The solver writes output files in JLD2 format to the `jld2_files` directory.
- Paraview Files: The solver writes Paraview-compatible files to the `vtk_files` directory.

If these directories are not present, they will be created automatically. Ensure the program has write privileges to these directories.

### 求解器运行要求
1. 网格文件目录：
求解器默认会在名为`mesh_files`的目录中读取网格文件，可通过向求解器传入相关参数修改该路径。

2. 输出目录：
- JLD2文件：求解器会将结果以JLD2格式写入`jld2_files`目录。
- Paraview格式文件：求解器会将兼容Paraview的文件写入`vtk_files`目录。

若上述目录不存在，程序会自动创建，请确保程序对这些目录拥有写入权限。

### Julia 安装
Julia 可从[官方网站](https://julialang.org/downloads/)下载安装。
