Using VPUT after a restart

Using VPUT after a restart

Using VPUT after a restart

(OP)
Hi everyone,
I am doing a thermal transient analysis. I have to restart the analysis in do-loops. Inside this loop I also have an inner do-loop in which I change the loading condition ans solve in a trial-and-error fashion until I find the correct loading condition for that load step.
For solving the problem at each inner do-loop I need to apply temperatures from the previous finalized load step as the initial condition. I use LDREAD,TEMP,last,,,2,'file','rth',' ' for this purpose.
However, it appears that within the inner loop this command reads the data from the last trial-and-error run, as opposed to the end of the previous load step. So I tried to save the results from the last finalized load step in an array and apply it during the trial and error via *VPUT, before I issue the LDREAD command. However, I get the following error message:

"data record does not exist for the vput of some node entities requested"

Any help or suggestion is really appreciated.
Thank you in advance for your time and help.

Ashton
