Dear Mr. Papazafeiropoulos,
Thank you very much for your response.
My problem is that I want to simulate the fluid flowing inside the pipes, which creates heat flow from the inlet to the outlet of the pipe. This can be simulated in Abaqus only by specifying the mass flow rate and only forced convection elements can be used. This is why I don’t know if I can use temperature-displacement elements for my problem.
However it would be very helpful if you shared with me your .inp file and try to find a solution using these elements.
Best regards,
Dimitris

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.
