  I am simulating the thermal stress developed in a rocket nosecone due to the temperature but I have no idea which boundary condition to apply. Can anyone please give me an idea?

  Put a Remote Displacement, Behavior = Deformable on the back circular face of the rocket. Set all six DOF to 0. The thermal expansion will be relative to a point at the center of that face. You have the imported temperature load already, which is the other boundary condition.

  You could also put an external Pressure load on the nose cone that comes from a CFD solution.
