Applying absolute HYDRA temperatures in ASE (TEMP NR T1=T2)

Hello,

I am trying to apply transient temperature fields from HYDRA in ASE and extract the structural response for different time steps.
In ASE I create load cases using:
loop#i #lf_n+1
if #i>0
STO#ilf (#ilf+1)

  syst prob line

  STO#mt   #time(#i+36)
  LET#RET XLS.WRITE(#i+2,4,#mt)

  lf #plf+#ilf EGY  1.0 FAKT #lf_fak TYP T     BEZ  #lf_fak
    TEMP NR   T1                   T2                   NRG       FAKT
         31   #mt                  #mt                  -         1

According to the documentation, when T1 = T2, the temperature field at this time should be applied.but the extracted structural results (displacements) are exactly identical for all time steps. Could you give me some hint how to solve this problem?

P.S.I am using Sofistik 2023.

Kind regards,

Sanaz

Dear Ms. Barabadi,

I have examined the sample file “bric_hydra_dt2h.dat” and found that the start time T1 can indeed be entered as 0.

TEMP NR 31 T1 0 T2 #mt NRG - FAKT 1

In this case, the temperature difference between start time 0 and T2 is passed. The option with T1=T2 does not appear to work as described in the manual. I will pass this information on to the author.

Mit freundlichen Grüßen / with kind regards
