Dear Miladm2, I am trying to develop an OpenSees Model in order to assess the seismic performance of The Steel Buried Pipeline as you would like to do. After I read your message, I think that we deal with same problem. Is it possible for you to share your input with me? I will appreciate If you can ...

Dear Vesna, Thank you for your reply. Although I added the convergence loop presented in web site, I got same message for each solution algorithm. Also, are the displacement time histories given after analysis in meter unit? or inch? because the recorder object defined for obtaining displacement tim...

Hi, I am trying to model pipeline with lead caulked pipe joints. The input of my model is below, when I run my input, I got an error message below; " WARNING: CTestEnergyIncr::test<> - failed to converge after: 100000 iterations NewtnRaphson::solveCurrentStep<> - the ConvergenceTest object fail...

I have 3 inertial DOF for my model. X, Y and Rotational Z.

I have created my pipeline model and when I run my input, I encounter such an error; WARNING BandGenLinLapackSolver: solve <> -LAPACK routine returned 14 domain error: argument not in valid range while executing "expr pow($lambda,0.5)" invoked from within "set omega [expr pow($lambda,...
