Abaqus Error

[xenger]

Hi everyone,
i'm currently trying to analyse a 2D planar wire truss system undergoing a temperature rise to measure the level of expansion of the truss sides. however when submitting the job for analysis i get the error message: "DEGREE OF FREEDOM 11 AND AT LEAST ONE OF DEGREES OF FREEDOM 1 THRU 6 MUST BE ACTIVE IN THE MODEL FOR *COUPLED TEMP-DISP. CHECK THE PROCEDURE AND ELEMENT TYPES USED IN THIS MODEL."

can anyone help with how this can be resolved? is a "coupled temp- displacement" the correct step to be using for a simple rise in temperature? i've tried changing the element type in the mesh to truss but this hasn't helped.

any replies would be greatly appreciated.

You don't need coupled temperature-displacement unless you are solving for temperatures as well as displacements. If you're just applying temperatures then do that through predefined field in the load module, using the normal elements for a truss.
