Dear Mr. Skordas,
There are no diffusive heat transfer truss elements in Abaqus, and therefore, the embedded element technique cannot be used for heat transfer analysis. Besides this, I assume that the concrete piles need to include displacement and rotational degrees of freedom in the analysis. Heat transfer analysis cannot be used for models containing displacement and rotational degrees of freedom.
However, there are coupled temperature-displacement solid elements (C3D8T) and coupled temperature-displacement truss elements (T3D2T), and therefore, you can perform a coupled temperature-displacement analysis (*COUPLED TEMPERATURE-DISPLACEMENT) using these truss elements embedded in the solid elements.
I can share with you an example input file with which a simulation containing T3D2T elements embedded in C3D8T elements is performed.
Best regards,
