Bilin Material

[mar]

Hello all,

Hope you are doing well. Is the Bilin material in the new update of OpenSees? I have updated to OpenSees 2.4.10 and I ran the dynamic example on your website (I believe is Dr. Lignos) and it did not converge. I hope you can help me on this. Thanks!!!

Sincerely,
Mar

I encountered this problem as well when I downloaded it. Just decrease the analysis time step and it'll be ok.

Hi,

Thanks for your reply. I changed the time step of analysis and it still didn't converge. I guess it must be the revision that I got from svn. If you have any other suggestion please let me know. Thanks again.

The only thing I could suggest,if you want to experiment with this example,is to increase the tolerance.If you are more worried about the opensees application,try to check out a more stable revision.Now which one, you will have to do a little search on your own.

However even the 2.4 version of opensees (downloaded the application,not the code from svn) doesn't converge.dt=0.005 is fine though.

for those of you who build OpenSees, Dimitrios has provided new source code. You will need to use scv to check it out and build the .exe. i will update the .exe, 2.4.0.10 or 2.5.0 soon. others are sending code that is also getting added.
