Heat transfer analysis HETVAL

[itbitb]

Dear Abaqus users,

I have problem need for advice: In heat transfer analysis, I want to input temperature values for every elements (or nodes) at every time steps during analysis. What subroutine I should use? HETVAL? And how to use it? because Abaqus manual for HETVAL is not much and not clear.

Thank you very much for your time

Best regards,

I believe that you can directly specify the temperature by using the temperature degree of freedom (DOF). I believe it is DOF=11 or 12.
Check the manual for more details.

Dear Mr. Jorgen,

Would you please to give me a brief explanation about "temperature degree of freedom". I cannot find its definition in the manual.

Thank you very much

Check out, for example, Section "25.1.4 Three-dimensional solid element library" in the Analysis User's Manual. That section specifies that the temperature DOF is #11.
