Abaqus参数化模型自动六面体网格划分脚本教程

```
# 进入交互式命令行界面
session.journalOptions.setValues(replayGeometry=COORDINATE, recoverGeometry=COORDINATE)

# 定义长方体的几何参数
lx = 1.0
ly = 2.0
lz = 3.0

# 创建模型和部件
import part

model = mdb.Model(name='Model')
part = model.Part(name='Part', dimensionality=THREE_D, type=DEFORMABLE_BODY)

# 创建长方体
import sketch
import geom
import mesh

s = mdb.models['Model'].ConstrainedSketch(name='__profile__', sheetSize=20.0)
s.rectangle(point1=(0.0, 0.0), point2=(lx, ly))
part.BaseSolidExtrude(sketch=s, depth=lz)
s.unsetPrimaryObject()

# 划分六面体网格
part.setMeshControls(regions=part.cells, elemShape=HEX, algorithm=MEDIAL_AXIS)
part.setElementType(elemTypes=(ElemType(elemCode=C3D8R, elemLibrary=STANDARD), ElemType(elemCode=C3D6, elemLibrary=STANDARD)), regions=(part.cells,))
part.generateMesh()

# 修改参数
lx = 2.0
ly = 3.0
lz = 4.0

# 重新生成网格
session.viewports['Viewport: 1'].setValues(displayedObject=part)
part.regenerate()
