Previously converged analysis failed when using Release 2.5

[ftong]

Hi everyone,

I have a few analyses that were run in March 2016 and converged well. However, they failed when I run them using the identical .tcl scripts using OpenSees Release Version 2.5.0. I cannot remember the exact version that I used in March 2016. It should be the latest release by that time.

Did anyone encounter the same problem? Can anybody advise how to resolve it? Where can I get the past releases of OpenSees?

Thanks.
Fei.

Hello Fei,
I found a similar proble when I use plates with LayeredShells. Finally, I ended up using an old OpenSees version, exactly Version 2.5.0 (rev 6477) 64-Bit
If you want this version, post your email and I'll send you.

Hi dgale,

Thanks for your reply. I also searched for older releases and finally came to the identical version 2.5.0 (rev6477) as what you use. It works for dynamic analyses but does not work for static pushover analyses.

Thanks.
Fei.
