Hello, i am using python script for running multiple dynamic simulation. For the cases where plb file is used i am getting playback model file not found error. .plb file is in the same location where dyr files are placed. Other simulation in the loop is running fine where plb is not used. For dyr files with plb as gives an warning in PSSE as file in use OpnApplFil/OPENSEA

When running dynamic simulation through Python scripts, the Playback model (.plb) file needs to be in the same folder as the Python script. (.Sav) & (.Dyr) files can be anywhere as their path can be constructed using Python. As the (.plb) path can not be built it should be in the working folder. The working folder is where your script is kept not where the dyr or sav file is stored

Can you paste the full error message? Is it a file not found error, or a file in use error?

One idea, try reducing the plb file name to just 2 characters. This was required in v33, and I don't think v34 has that restriction, but it's worth trying.

If it is actually a file in use error, try ending your loops with pssehalt_2() to try to release any lock on the plb file.

Will pssehalt_2 l() stop my entire simulation?

I am running 100 simulations , File in use message is pooping only for thouse simulation where i have playback model referred in dyr file.

The playback file must be in the working folder.

sav file in folder A where as dyr file is in folder B along with plb file

Anil ( 2024-10-09 11:37:04 -0600 )edit

Make sure the plb file is in PSSE´s working folder!

perolofl ( 2024-10-09 12:47:43 -0600 )edit

Can you please explain PSSE´s working folder! I construction path of sav & dyr seperately and use them as required. As plb file is in the same folder of dyr i assume it takes it automatically

Anil ( 2024-10-09 13:08:06 -0600 )edit

I even kept sav , dyr and plb in same folder still the error persist

Anil ( 2024-10-09 13:12:27 -0600 )edit

Are you running PSSE from the GUI or from pyrhon?
