            # Coreform Cubit Mesh Export

Coreform Cubitから様々な形式のメッシュファイルをエクスポートするPythonライブラリ

## インストール方法

### PyPIから直接インストール（推奨）
```bash
pip install --upgrade coreform-cubit-mesh-export
```

### Cubit内蔵Pythonの場合
```bash
cd "C:\Program Files\Coreform Cubit 2025.3\bin\python3\"
python.exe -m pip install --upgrade coreform-cubit-mesh-export
```

### 開発版をGitHubからインストール
```bash
pip install git+https://github.com/ksugahar/Coreform_Cubit_Mesh_Export.git
```

### ローカルインストール（開発用）
```bash
git clone https://github.com/ksugahar/Coreform_Cubit_Mesh_Export.git
cd Coreform_Cubit_Mesh_Export
pip install -e .
```

## サポートしているファイル形式

- **Gmsh形式**
  - バージョン2.2（完全サポート）
- **Nastran形式**
  - 2Dメッシュ
  - 3Dメッシュ
- **MEG形式**（ELF用）
  - 2Dメッシュ
  - 3Dメッシュ
- **VTK形式**
  - メッシュのみ（Legacy VTK形式）

## 使い方

### Cubit内での使用例

Cubitでメッシュ生成後、以下のようにPythonスクリプトを実行します：

```python
# Cubitコマンドライン
play "export_mesh.py"
```

`export_mesh.py`の内容例：

```python
import cubit_mesh_export

# Nastran形式でエクスポート
FileName = 'output/model.nas'
cubit_mesh_export.export_3D_Nastran(cubit, FileName)

# Gmsh形式でエクスポート
FileName = 'output/model.msh'
cubit_mesh_export.export_3D_gmsh_ver2(cubit, FileName)

# VTK形式でエクスポート
FileName = 'output/model.vtk'
cubit_mesh_export.export_3D_vtk(cubit, FileName)
```

## 関数一覧

### Gmsh形式
- `export_gmsh_ver2(cubit, filename)` - Gmsh v2.2形式で3Dメッシュをエクスポート 2次要素に対応

### Nastran形式
- `export_Nastran(cubit, filename, DIM="2D|3D", PYRAM=True|False)` - 2D/3DメッシュをNastran形式でエクスポート、PyramidをHexに変換、1次要素のみサポート

### MEG形式（ELF用）
- `export_meg(cubit, filename, DIM="T|R|K", MGR2)` - T:3次元、R:軸対称、K:2次元、MGR2で空間節点を指定

### VTK形式
- `export_3D_vtk(cubit, filename, ORDER="2nd")` - Legacy VTK形式でエクスポート、2ndで2次要素に対応

## 要件

- Python 3.7以上
- NumPy >= 1.20.3
- SciPy >= 1.6.3
- Coreform Cubit（メッシュ生成用）
