Mapping KinematicHardening fields from an odb to a new mesh...

Mapping KinematicHardening fields from an odb to a new mesh...

Mapping KinematicHardening fields from an odb to a new mesh...

(OP)
I am trying to map a KinematicHardening field (i.e., equivalent plastic strains and initial backstress tensor) from an odb to a new mesh.

I can map the stress field using the following command:
mdb.models['MY_MODEL'].Stress(distributionType=FROM_FILE, fileName='Job-1', increment=10, name='TEST', step=1)

When I query the KinematicHardening object from the Scripting Reference Manual, it says that the region argument "... is also ignored if the predefined field has a distributionType member available, and distributionType=FROM_FILE or FROM_FILE_AND_USER_DEFINED." However, a FROM_FILE distribution type does not appear to be supported. Reading on, it almost appears as though I can use a mapped ANALYTICAL_FIELD distribution type. However, since only a scalar ANALYTICAL_FIELD is supported in Ver 6.12, I don't see how this is possible given the required/optional arguments to the KinematicHardening object.

My only other option appears to be the HARDINI user subroutine... Here, does "material point" refer to an integration point? Are values interpolated as appropriate or must they all be given?

Is there another way to map a KinematicHardening field or is there something I have overlooked? If not, could someone please forward a working copy of a HARDINI user subroutine.

Thanks
-Dave
