Abaqus CAE: difficulty generating friction heating in coupled temp-displacement model

[TopGere]

Hi,

I'm trying to generate frictional heating in a coupled thermal-mechanical model with cyclical loading. Heating should occur at the edges of an elliptical hole in the center of a plate. I've created the interaction property, which has thermal and mechanical components, and the self-contact property, but I'm still getting a warning that says:

"Heat transfer on surface assembly_surf-1 may not be correct due to the balanced slave-master approach used in self-contact.

Surface interaction intprop-1, associated with one or more contact pairs with surfaces having underlying elements with temperature and displacement degrees of freedom, does not have any thermal interaction defined. No thermal interaction will occur."

I've asked around, but I haven't come across anybody who's used Abaqus for this purpose. I figured this might be the place to find help.

Here are the parameters which I have used:

Property Module --
Density, damping, Young's modulus, Poisson's ratio, expansion coefficient with reference temperature, specific heat, thermal conductivity, and viscoelastic properties

A coupled temp-displacement step

Interaction Module --
Self contact: Tangential w/ friction coefficient, normal w/ penalty, heat generation

Load Module --
Uniform periodic load, predefined temperature field

Mesh Module --
Coupled temp-displacement elements


Thanks in advance, and let me know if any more specific information is necessary and I will provide it.
