Strt problem between GUI and python
Hi all, I used IEEE-39bus model which has 1 GAST2A model.
First, I used GUI to run STRT/RUN. Everything is normal. The message showed below. However, I tried to change this one into python. When I applied STRT API, the results are not the same.
Pls, help me with this case. I really did not know why. The second result is copied from (STRT) .out file when I used python.
the first result (1)

The "second result" has all of the machine initial condition result parameters at zero, which makes me think that you have not loaded some of the files correctly. Are you sure that you have loaded the CNV and SNP files correctly using Python before trying to do the STRT command in Python?
