利用Python输出Abaqus的结果数据
from odbAccess import *#打开Ddb文件
odb = openOdb(path='viewer_tutorial.odb')
#创建变量lastFrame，得到载荷步Step-1的最后一帧
lastFrame = odb.steps['Step-1'].frames[-1]
# Create a variable that refers to the displacement 'U'
# in the last frame of the first step.
#创建变量displacement ，得到最后一帧的位移场数据
displacement = lastFrame.fieldOutputs['U']
#创建变量center，得到节点集PUNCH
center = odb.rootAssembly.instances['PART-1-1'].\
nodeSets['PUNCH']
#创建变量centerDisplacement，得到region center的位移场数据
centerDisplacement = displacement.getSubset(region=center)
#输出各种信息，该节点集只有一个节点
for v in centerDisplacement.values:
print 'Position = ', v.position,'Type = ',v.type
print 'Node label = ', v.nodeLabel
print 'X displacement = ', v.data
print 'Y displacement = ', v.data
print 'Displacement magnitude =', v.magnitude
odb.close()
输出结果为：
The resulting output is
Position = NODAL Type = VECTOR
Node label = 1000
X displacement = -8.29017850095e-34
Y displacement = -76.4554519653
Displacement magnitude = 76.4554519653
