Thank you Frank, I have solved the issue with release 5921 on 32bit and 64bit. Basically on 32bit machine the ArcLength integrator "StaticIntegrator *INTEG_2 = new ArcLength(1.0)" performs the analysis beyond the elastic limit of the structure with the default value of the parameter alpha=...

Dear Frank I have installed different repositories of OpenSees Libraries on Ubuntu 32bit and 64bit architecture. I have different results when I run the code on 32bit and 64bit machine. I perform static nonlinear analysis of grillages. I have checked the steps line by line on each platform and unitl...

Hello Frank, Thank you for your suggestion. Yes I am using ForceBeamColum elements. I have monitored the output of each step of analyze. apparently the problem was due to the "Element Length", that i use to read from the model to calculate the load. In same iterations some elements returne...

Hi Frank, I have tried to follow your instruction, but apparentely I could not solve the issue described above. after a certain number of pushovers in a monte carlo, the program at a point of the static analysis "analyze(1)" get hanged and does not return anymore. the recorder get in the o...

Thank you Frank,
I am not using nDmaterial.
I will try to follow your instructions and I will let you know.

Hello Opensees community, I hope you could please help me to solve this issue. I have experienced a problem with the class "StaticAnalysis" and the command "analyze". briefly, I have a loop where the model is built and the load is applied in a load control, where the number of st...
