# Re: Buckling analysis not solving

That text is from the log/statistics file or summary file. They are located in a folder under "my model name.ds_data\design scenario number" and are named DS.LG6 and DS.L6, respectively. They can be opened with Notepad or a word processor.

So if your model name were "Buckle 1.fem" and this analysis is in design scenario 3, you would want to look for these files:

"buckle 1.ds_data\3\DS.LG6"

"buckle 1.ds_data\3\DS.L6"

FYI. If you search the Help for the words "File Extensions", you will locate the page that explains the directory structure and lists all of the extensions.

Good luck. I hope you find what you are looking for.
