Re: record global stiffness matrix

Hello,
Can somebody please post examples about how to modify the files mentioned above in order to record global stiffness for each time, for any solver? I have checked the files as described above, trying for a long time, but couldn't make it. I really need this. Please, someone help me. Thanks.

nonconvergence issue

Hi, In my code, I am trying to do several incremental dynamic analyses for an inelastic structure. For convergence issue, I used the related part of the given examples. I just wonder how I can understand that I am having a collapse (instability of the structure), or which convergence warning let me ...

Incremental Dynamic Analysis

Hi, I am trying to do Incremental Dynamic Analysis. As I understand, I only need to scale the gorund motion and do time history analysis each time. I started with an example from the manual. source Ex8.genericFrame3D.build.Wsec.tcl source Ex8.genericFrame3D.analyze.Dynamic.EQ.Uniform.tcl It seems th...
