I am also working with Bouc-Wen model. Can you please share the parameters you used?

I have increased the tolerance to a value equal to 1e-5 and increased iteration number to 100 and I got no warning.
I hope the problem have been solved.

Dear all, I have run the following script for the problem of base isolation but got these warnings. However I end up get the results for the node displacement and I am not sure if they are correct. 1.What should I edit so that I get no warning? 2. Under these warnings will the results be correct or ...

Thank you very much for your kind response, let me work on it.
What about the zero length between node 2 and 4,where i want to include the impact material?
Can you please comment something!
Thank you.

Hi everyone, I have tried to run the following script for the problem of 2DOF system considering impact between the base and the moat wall under earthquake loading. The program(opensees) stopped running,i don't know why. Can someone help me to check where is the problem and suggest what do. Thank yo...

@Prafullamalla I sent you the files for opensees navigator hope you received them.

Ok, I will try to send you set up files.

I was able to plot the graphs for responses and the results seem to be OK,thank you once again.Have you tried to do this example using opensees navigator?

Well explained,i understand now.Thank you.I will plot graph.

Yes i checked the output files with results(did not plot the graph),does it means that convergence error should be ignored and there is no effect to the results? How do you plot graph?

No I tried it first on opensees navigator, but when I tried it in opensees it had a convergence error.

No it is not convergence error.I can send you an image for the error message ,and please if you don't mind can you text me your email to my email address nyangip@yahoo.com, I would like to discuss in detail and I may have some question on your model that I still need some explanation, I am in Wuhan.

I have tried to model this 3DOF system using opensees navigator and I get error message.can you help me please to figure out the problem # Coded by Prafulla Malla, Sichuan University # Structural Response 3DOF # Report Vibration Control # X--*************--X --************--X----************--X # 1F...

Still need your help,i could not be able to figure out this.
I will appreciate.

Thank you for sharing such a good example.Will you kindly share a typical example for base isolated 2DOF system subjected to ground motion(earthquake),i was trying to do the same and blocked somewhere.Will appreciate for your help.
