The new release broke all my models containing fibers.
Please someone tell me where I can find release 3.0.0.

Thanks

In addition to this printA only seems to print 6 significant digits. Any way to get more significant digits with printA?

Thank you very much for your reply.

I noticed that instead of creating an additional node to act as the master node for a rigid diaphragm, using one of the diaphragm constrained nodes as the master node does not influence the results (modal analysis). Are there any dangers with this? Is there any reason why creating a "virtual&qu...

Thank you for your reply. This is what I currently do; however the central difference gives warnings: "WARNING: CentralDifference::domainChanged() - assuming Ut-1 = Ut WARNING FullGenLinLapackSolver::solve() - lapack solver failed - 2 returned WARNING NewtonRaphson::solveCurrentStep() -the Line...

Hi everybody, I was wondering is there a simple way to get the global mass-M and stiffness-K matrices that the "eigen" command uses (http://opensees.berkeley.edu/wiki/index.php/Eigen_Command). I saw you can get some kind of K and M from running a one-step analysis and using "printA&qu...

Thank you for your reply. This is my current plan.

Hi I'm new to OpenSees, just installed the software, I hope I'm posting this to the right place. I am going through some of the examples. I try to run this one: http://opensees.berkeley.edu/wiki/index.php/Eigen_analysis_of_a_two-storey_one-bay_frame but I get my modeshape plot windows not responding...
