LS-DYNA: End-of-file Error using *USER_LOADING_SET
 
1 Attachment(s)
Hi,
I'm new to ls-dyna and simulation as a whole and am getting an error where I don't understand whats wrong.
In my dummy simulation I'm only doing a themal analysis of a simple cube and I'm trying to apply a user load through the keyword: *USER_LOADING_SET in the .k input file:


Code:

*USER_LOADING
      1.0      0.0      0.0      0.0      0.0      0.0      0.0      0.0
*USER_LOADING_SET
        1TEMPTN            1        0      0.0      0.0      0.0        0

A simulation with these Parameters result in a Error message:


*** Error 20680 (STR+680)
unexpected end-of-file


This is only the case when USER_LOADING_SET is used and not for only USER_LOADING but I need both.
I know I need to modify the code in dyn21.f of the ls-dyna code and I did but it doesn't reach the function loadsetud where I put my code.

It seems to me that there is a keyword missing that is not named in the manual?

If I use the option FORCEN instead of TEMPTN and do a stress analysis, it calls the load function as expected.
The keyword check in LS-PrePost has no errors and these are the control keywords for the TEMPTN case:


Code:

*CONTROL_SOLUTION
        1        0        0      100        0        1
*CONTROL_TERMINATION
      1.0        0      0.0      0.01.000000E8        0
*CONTROL_THERMAL_SOLVER
        1        0        111.00000E-4        8      1.0      1.0      0.0
        0      5001.0000E-101.00000E-4      1.0                          1.0
        0      0.0        0
*CONTROL_THERMAL_TIMESTEP
        1      0.5      0.011.00000E-4      0.1      1.0      0.5        0

Is there a additional keyword that I need to place for USER_LOADING_SET to work? Do you need additional information?
The cube is attatched in a zip.

Thank you for taking a look!
