damping ratio

thank you! But in that answer, you mentioned a readme file which I couldn't find there. Could you please tell me where I can get detailed instruction?

That posting redirect you to the post "Channels - tool to process outs files" for instruction to download the tool. The readme file is part of the release.

thankyou so much for the resources! However I am encountering the following issue. When in the dos window I type channels_chan_Pe_plt I get the following error: File "C:\Users\jsm20\Documents\code\Python\channels.py",line 139 in <module> ImportError: No module named Matplotlib

The ppt 'manual' says that additional python modules are needed: matplotlib, numpy, scipy, PyPDF2. With admin rights, in a DOS window, enter: pip install matplotlib. To run a damping calculation test, enter: channels chan_Pe_dmp

if I write pip install matplotlib,it shows "the system can not execute the specified program". What might cause this issue? is it compatible only with psse33 and python 2.7? Right now I was using psse34 and python 3.7

On a DOS window, change directory to c:\python37\scripts and execute the pip command. Channels is compatible with python 2.7, 3.7 to 3.9 and PSSe 33 to 35

The directory should be the location where the scripts folder is, right? for me it is C:\Users\erika\Desktop\s\channel\channels_JConto_20211031\SCRIPTs and in scripts folder should I move the chan_Pe_dmp file?

I would use "C:\Users\erika\Desktop\s\channel\channels_JConto_20211031" as the working folder, same where to open the DOS window, and place a copy of the ini file there. Inside the ini file, all paths should be relative to this working folder or use full absolute paths. Run: channels chan_Pe_dmp

now it is showing "channels"is not recogniuzed as an internal or external command. What should be done to fix this error?

I got that issue resolved now. But I have a question. After running that channels chan_Pe_dmp I got a plot. But an excel table should also be created showing the damping ratio, right? or where should I find the find the damping ratio now?
