ok thank you very much

Hi I am modeling a structure and I am trying to assign the different damping coeffcient for each element region using Region comanad and rayleigh. But for some reason I dont think it is working properly because when I print out acceleration the strucutre is oscilating like there is no damping. Do yo...

Hello, Does anybody know whether it is possible in OpenSees to extract the stiffness matrix of the structure after every timestep in the time history analysis?
Thank you

I have one more question is it possible to model hollow circular beam in OpenSees?

I opened it in GID just to see the geometry and then I defined elemets in GID and then created the tcl file from that just to chcek it if I done it correctly and it showed the same transformation for all elements. About the units the mass should be in kg/m or tons/m or kg/m^3 ? because I am not sure...

So basically I cannot make the model directly in the global reference system but I have to create it in the local and then rotate it as I want to have? Do I understand it correctly?

Hello, I have a quick question is it possible in Timoshenko elastic beam element somehow skip the part regarding coordinate-transformation when i am defining the element. I want to do it because my model is already in correct way but when I run the script I am getting message that it is rquired, so ...
