更新：
最近工作量比较大，逐渐意识到之前用.py文件进行宏录制的局限性，对这个程序进行了一部分改进，使它能够更方便的调用。之前的程序是将拆分间距和model名、part名确定的，每次调用都要更改里面的数据，我参照了知乎一位大佬的方法（链接https://zhuanlan.zhihu.com/p/84749135），做了如下改进：
from abaqus import *
from abaqusConstants import *
from caeModules import *
viewportName = session.currentViewportName#获取当前模型名
cobject=session.viewports[viewportName].displayedObject#cobject实际上是一个字典，里面包括当前模型的全部信息
modelNameDE=cobject.modelName#利用modelname函数将cobject中的模型名提取出来
# partNameDE=cobject.name #应用part的方法和model方法类似
# print(modelNameDE)
# print(partNameDE)
modelname=getInput('Are U sure that it is this model',modelNameDE)
number=getInput('what is the number of OCA','0.05')#getinput函数弹出一个对话框，给对话框提供一个默认值，可以简化操作
from driverUtils import executeOnCaeStartup
p = mdb.models[modelNameDE].parts['pad']
f, e, d = p.faces, p.edges, p.datums
t = p.MakeSketchTransform(sketchPlane=f[0], sketchPlaneSide=SIDE1, origin=(
-124.940785, -0.053036, 0.0))
s = mdb.models[modelNameDE].ConstrainedSketch(name='__profile__',
sheetSize=588.26, gridSpacing=14.7, transform=t)
g, v, d1, c = s.geometry, s.vertices, s.dimensions, s.constraints
s.setPrimaryObject(option=SUPERIMPOSE)
p = mdb.models[modelNameDE].parts['pad']
p.projectReferencesOntoSketch(sketch=s, filter=COPLANAR_EDGES)
session.viewports['Viewport: 1'].view.setValues(nearPlane=426.19,
farPlane=750.334, width=2.07316, height=0.843045, cameraPosition=(20.0515,
-0.17324, 588.262), cameraTarget=(20.0515, -0.17324, 0))
s.offset(distance=0.03, objectList=(g[5], g[4]), side=LEFT)
s.offset(distance=0.055, objectList=(g[5], g[4]), side=LEFT)
s.offset(distance=0.055+float(number), objectList=(g[5], g[4]), side=LEFT)
s.offset(distance=0.077+float(number), objectList=(g[5], g[4]), side=LEFT)
s.offset(distance=0.09+float(number), objectList=(g[5], g[4]), side=LEFT)
s.offset(distance=0.09+float(number)+float(number), objectList=(g[5], g[4]), side=LEFT)
s.offset(distance=0.12+float(number)+float(number), objectList=(g[5], g[4]), side=LEFT)
s.offset(distance=0.12+float(number)+float(number)+float(number), objectList=(g[5], g[4]), side=LEFT)
p = mdb.models[modelNameDE].parts['pad']
f = p.faces
pickedFaces = f.getSequenceFromMask(mask=('[#1 ]', ), )
e1, d2 = p.edges, p.datums
p.PartitionFaceBySketch(faces=pickedFaces, sketch=s)
s.unsetPrimaryObject()

在abaqus实际使用中，经常需要大量的重复操作，比如将abaqus中的模型拆分成十几个区域，此时在cae中操作很复杂，可以通过python二次开发进行批量操作。
rom abaqus import *
from abaqusConstants import *
from caeModules import *
from driverUtils import executeOnCaeStartup
#THERE IS A TEMP
f, e, d = p.faces, p.edges, p.datums
t = p.MakeSketchTransform(sketchPlane=f[0], sketchPlaneSide=SIDE1, origin=(
-124.940785, -0.053036, 0.0))
s = mdb.models[''].ConstrainedSketch(name='__profile__',
sheetSize=588.26, gridSpacing=14.7, transform=t)
g, v, d1, c = s.geometry, s.vertices, s.dimensions, s.constraints
s.setPrimaryObject(option=SUPERIMPOSE)
##THERE IS A TEMP
p.projectReferencesOntoSketch(sketch=s, filter=COPLANAR_EDGES)
s.offset(distance=0.025, objectList=(g[4], g[3]), side=LEFT)
s.offset(distance=0.075, objectList=(g[4], g[3]), side=LEFT)
s.offset(distance=0.110, objectList=(g[4], g[3]), side=LEFT)
s.offset(distance=0.160, objectList=(g[4], g[3]), side=LEFT)
s.offset(distance=0.190, objectList=(g[4], g[3]), side=LEFT)
s.offset(distance=0.240, objectList=(g[4], g[3]), side=LEFT)
p = mdb.models['oca_50um_30mm'].parts['pad']
f = p.faces
pickedFaces = f.getSequenceFromMask(mask=('[#1 ]', ), )
e1, d2 = p.edges, p.datums
p.PartitionFaceBySketch(faces=pickedFaces, sketch=s)
s.unsetPrimaryObject()
黑体为需要修改的语句
上图是一个拆分的简单例子，核心思路是：利用草图拆分功能，将底边向上偏置，进行模型的划分。python的二次开发实际上就是批量操作，具体操作是，首先通过abaqus.py文件，获取模型的底边数组为g[3],g[4]，然后进行偏置，这样做的优点是可以一键生成拆分，而且修改方便。不过这个方法只适用于简单模型，复杂模型的拆分并不适用。
