[quote="silvia"]try playing with the hysteretic material.[/quote]

I omitted to mention that I did try with hysteretic material but the results seem to be weird. Another suggestion?
If not, I'll keep trying with hysteretic material.
Thank you.

Hello, I've read the manual however, I couldn't find the proper material to model a only tension element. The material I want to model has the following stress-strain relationship: eps= -0.005 0 stress= 75.0 eps= -0.0025 stress=100.0 eps= -0.0000 stress=300.0 eps= 0.0025 stress=600.0 eps= 0.0050 str...

[quote="silvia"]the power of opensees is the ability to change your solution strategies if one doesn't work. that's what the example does. the variable ok tells you whether the analysis converged. if it didn't, it modifies the analysis and manages to get over that point and moves on.[/quot...

[quote="silvia"]that was the point of the example. it ran into convergence problems and it solved them to completion "DONE!" look at the script and look at the results.[/quote] Sorry, I didn't get the point. As I understood, examples9 are non-convergence cases, if so, how can I f...

Hysteretic material & Uniaxial Section

Hello OS community, Perhaps I misunderstood the manual but for a 2D model, I assigned an Hysteretic uniaxialMaterial to an Uniaxial section for a nonlinearBeamColumn element. Somebody knows whether it's conceptually correct? I'm trying to model a cable but I got the following error message: Domain::...

Nodalmasses in many elements

Dear all, hope somebody knows the answer to the following: 1. How can I declare a large number of nodes having the same nodal mass? Is there an abbreviation for: mass 1 $Mass1 $Mass2 0 . . . mass 500 $Mass1 $Mass2 0???? 2. In a parallel case, how can I define a large number of elements having the sa...
