Abaqus Script學習筆記

1 abaqus中的對象分為兩類,一類是容器對象(repository),例如steps(包含所有分析步)、frames(包含一個分析步中所有的frame)、fieldOutputs(包含一個frame中所有的場變量輸出)等等,它們本身是一個list,用len函數(shù)可以得到其所包含對象的數(shù)量(例如len(steps1)),還可以用keys函數(shù)列出所有的成員,詳見Abaqus Scripting User's Manual->8.5.5。例如:

for stepName in odb.steps.keys():

print stepName

輸出為:

Step-1

Step-2

Step-3

##################

for fieldName in lastFrame.fieldOutputs.keys():

print fieldName

輸出為:

COPEN TARGET/IMPACTOR

CPRESS TARGET/IMPACTOR

CSHEAR1 TARGET/IMPACTOR

CSLIP1 TARGET/IMPACTOR

LE

RF

RM3

S

U

另一類是單一對象(singular).例如steps中所包含的一個step對象,這類對象可以用“step1.__members__”這樣的方法查詢它所有的成員;

2 下面的例子演示了用elementSets得到一個特定的set,配合getSubset輸出指定set的計算結(jié)果,關于getSubset函數(shù)中region參數(shù)的用法參見Abaqus Scripting User's Manual->8.5.7。

topCenter = odb.rootAssembly.instances['PART-1-1'].elementSets['CENT']

stressField = odb.steps['Step-2'].frames[3].fieldOutputs['S']

# The following variable represents the stress at

# integration points for CAX4 elements from the

# element set "CENT."

field = stressField.getSubset(region=topCenter,

position=INTEGRATION_POINT, elementType = 'CAX4')

fieldValues = field.values

for v in fieldValues:

print 'Element label = ', v.elementLabel,

if v.integrationPoint:

print 'Integration Point = ', v.integrationPoint

else:

print

# For each tensor component.

for component in v.data:

# Print using a format. The comma at the end of the

# print statement suppresses the carriage return.

print '%-10.5f' % component,

# After each tuple has printed, print a carriage return.

print

輸出為:

Element label = 1 Integration Point = 1

S : 0.01230 -0.05658 0.00892 -0.00015

Element label = 1 Integration Point = 2

S : 0.01313 -0.05659 0.00892 -0.00106

Element label = 1 Integration Point = 3

S : 0.00619 -0.05642 0.00892 -0.00023

Element label = 1 Integration Point = 4

S : 0.00697 -0.05642 0.00892 -0.00108

Element label = 11 Integration Point = 1

S : 0.01281 -0.05660 0.00897 -0.00146

Element label = 11 Integration Point = 2

S : 0.01183 -0.05651 0.00897 -0.00257

Element label = 11 Integration Point = 3 ...

3 Abaqus python輸入行的tab自動補全功能,詳見Abaqus Scripting User's Manual->6.1.2。
