abaqus系列之二维图形导出

如何通过二维odb或者inp文件网格导出二维图形，进而extrude生成三维网格。

答案：script命令：

PartFromOdb(...)

PartFromInstanceMesh(...)

Part2DGeomFrom2DMesh(...)

PartFromExtrude2DMesh(...)

PartFromSection3DMeshByPlane(...)

以下的两个py文件为abaqus 6.6版本支持的py文件

参考py文件（从odb文件中导出）：

"""

Reads the output database file and imports the deformed shape of

the billet at the end of step 1 as an orphan mesh part. The

orphan mesh part is then used to create a 2D solid part which

can be meshed by the user.

"""

from abaqusConstants import *

import part

# NOTE: USER MUST DEFINE THESE VARIABLES.

odbName = 'Job-2.odb' # Name of output database file.

modelName = 'Model-1' # Model name.

orphanInstance = 'PART-1-1' # Deformed instance name.

deformedShape = DEFORMED # Shape.

angle = 15.0 # Feature angle.

importStep = 2 # Step number.

# Import orphan mesh part.

orphanBillet = mdb.models['Model-1'].PartFromOdb(fileName=odbName,

name='orphanBillet', instance=orphanInstance, shape=deformedShape, step=importStep)

# Extract 2D profile and create a solid part.

newBillet = mdb.models['Model-1'].Part2DGeomFrom2DMesh(name='newBillet', part=orphanBillet, featureAngle=angle)

newBillet1 = mdb.models['Model-1'].PartFromExtrude2DMesh(name='newBillet1', depth=20,

part=orphanBillet,

elementSize=5)

print 'Deformed billet is now ready for rezoning.'
