各位大佬请教一下,我在后处理过程中,进行了场输出的操作,在.rpy文件中得到了该步骤的命令,**该命令在abaqus里面为啥会报错呢,如命令如下
odb = session.odbs['D:/abaqus/temp/WU-result/Square/N8/Job-N8U14.odb']
session.writeFieldReport(fileName='RFU14rpt.rpt', append=OFF,
sortItem='Node Label', odb=odb, step=0, frame=149, outputPosition=NODAL,
variable=(('RF', NODAL, ((INVARIANT, 'Magnitude'), )), ('U', NODAL, ((
COMPONENT, 'U1'), )), ), stepFrame=SPECIFY)
输入后提示
NameError: name 'NODAL' is not defined
这是怎么回事
