使用Python脚本从Abaqus ODB节点集提取HFL Magnitude返回空列表的问题求助

我最近在写Python脚本，想从Abaqus ODB文件的指定节点集里提取热通量的HFL Magnitude数据，但脚本运行后总是返回空列表。但有意思的是，用几乎完全相同的逻辑提取温度NT11的时候，就能正常拿到数据，完全没问题。

下面是我用来提取HFL的脚本，后面附上了能正常工作的NT11提取脚本，恳请各位帮我排查下问题所在：

提取HFL的脚本 #

from odbAccess import *
import numpy as np

# Path to the ODB file
path0 = 'E:/Job-TCMT.odb'

# Open the ODB file
odb = openOdb(path=path0)

# Name of the node sets
nodeset_1 = 'NODESET-ZCT-1'
nodeset_2 = 'NODESET-ZCT-2'

# Extract the node sets
mySet_1 = odb.rootAssembly.instances['PART-1-1'].nodeSets[nodeset_1]
mySet_2 = odb.rootAssembly.instances['PART-1-1'].nodeSets[nodeset_2]

# Extract the last frame of the step
lastFrame = odb.steps['Step-1'].frames[-1]

# Heat flux field (HFL magnitude)
HFL = lastFrame.fieldOutputs['HFL']

# Get heat flux values for the two node sets
mySetHFL_1 = HFL.getSubset(region=mySet_1)
mySetHFL_2 = HFL.getSubset(region=mySet_2)

# Retrieve heat flux values for each node set
hfl_values_1 = [v.magnitude for v in mySetHFL_1.values]
hfl_values_2 = [v.magnitude for v in mySetHFL_2.values]

# Combine heat flux values from both sets
all_hfl_values = hfl_values_1 + hfl_values_2

# Calculate the average heat flux
HFL_moyenne_arith = np.mean(all_hfl_values)

# Display the result
print('The average heat flux (arithmetic) =', HFL_moyenne_arith)

# Close the ODB file
odb.close()

能正常工作的NT11提取脚本 #

from odbAccess import *
import numpy as np

# Path to the ODB file
path0 = 'E:/Job-TCMT.odb'

# Open the ODB file
odb = openOdb(path=path0)

# Name of the node sets
nodeset_1 = 'NODESET-ZCT-1'
nodeset_2 = 'NODESET-ZCT-2'

# Extract the node sets
mySet_1 = odb.rootAssembly.instances['PART-1-1'].nodeSets[nodeset_1]
mySet_2 = odb.rootAssembly.instances['PART-1-1'].nodeSets[nodeset_2]

# Extract the last frame of the step
lastFrame = odb.steps['Step-1'].frames[-1]

# Temperature field (NT11)
TEMP = lastFrame.fieldOutputs['NT11']

# Get temperature values for the two node sets
mySetTemp_1 = TEMP.getSubset(region=mySet_1)
mySetTemp_2 = TEMP.getSubset(region=mySet_2)

# Retrieve temperatures for each node set
temp_values_1 = [v.data for v in mySetTemp_1.values]
temp_values_2 = [v.data for v in mySetTemp_2.values]

# Combine temperatures from both sets
all_temp_values = temp_values_1 + temp_values_2

# Calculate the average temperature
Tint_moyenne_arith = np.mean(all_temp_values)

# Display the result
print('The average temperature (arithmetic) =', Tint_moyenne_arith)

# Close the ODB file
odb.close()
