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,

Anh

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.

Dear Dr Jorgen,
I was wondering if you could give me some advice in this area as well. I am trying to find the average temperature of a surface and then substitute this average to a sink temperature in FILM subroutine. I don't have any ideas how to define the average temperature of a surface. I used TEMP subroutine function but it is for average temperature of an element.
Please find a copy of subroutine below:
SUBROUTINE FILM(H,SINK,TEMP,KSTEP,KINC,TIME,NOEL,NPT,
1 COORDS,JLTYP,FIELD,NFIELD,SNAME,NODE,AREA)
C
INCLUDE 'ABA_PARAM.INC'
C
DIMENSION H(2),TIME(2),COORDS(3), FIELD(NFIELD)
CHARACTER*80 SNAME
H(1)=1.5
SINK=TEMP
RETURN
END

Thank you !
