Issues with Python script for *SIGINI subroutine

[coolFL]

Hello everybody, 

I am doing one residual  stress simulation. I have two part instances which come in contact and one of them has non-uniform residual stresses from the beginning. I have written *SIGINI subroutine to apply non-uniform initial stress. I tried to apply this stress using python script which is as follows:

a1=mdb.models['208_Bearing_Residual_Run_2'].rootAssembly
e1=a1.instances['Inner Raceway-1'].elements
elements1 = e1.getSequenceFromMask(mask=('[#ffffffff:3972 #1 ]', ), )
region=a1.Set(elements=elements1,name='Set-20')
mdb.models['208_Bearing_Residual_Run_2'].Stress(name='Predefined Field-1',region=region, distributionType=USER_DEFINED)


After running this script, Abaqus does create predefined field. But it doesn't recognize that distribution type is non-uniform and needs to taken from user defined subroutine *SIGINI. 

Is there anything wrong with the Python script?

Any input is appreciated, 

Thank you in advance, 

Sincerely, 

Nik

Have you checked that your model submission includes a path to the subroutine?

Yes it does.
