Re: Stiffness matrix

Yes, it is You must use system FullGeneral and after your analysis, you must add the following: set controlTime [getTime]; set ok [analyze 1 $dtcal]; <----------Your analysis set Kfile [join [concat "K" "$controlTime" ".out"] "" ] printA -file $Kfile;

max step number in a simulation

Hello, I would like to know how many steps the ground motion has, when I use the script bellow. I mean, I have a file with the ground motion acceleratons but when I introduce it to OpenSees by "set AccelSeries " Series -dt $dt -filePath $outFile -factor $GMfatt" " I would like to know the vector siz...

Re: Triangle elements

Some elements are not created for parallel compiting. In my case, I use section LayeredShell which doesn't work in parallel.

Hello, I think I installed well everything but an error message comes up like this: "Function Load Error!The version of DLL maybe incorrect" So I guess that I put the CuSPSolver.dll in a wrong folder. Could someone say me where I have to put CuSPSolver.dll? (I mean the correct address) Thanks in adv...

bug in time outputs

Hello, Could you help to understand what happen with time in my outputs? I post the code below, just run it and see the output disp2.out at the first column. My idea with this code is to give an input of sp displacement in a node and to obtain the forces in the spring. If you think I need a special ...

OpenSees vs Sap2000

Hello everyone,
I would like to open a foro to know what are the strengths and weaknesses between OpenSees and SAP2000 if we only take into account the numeric simulation. I mean without taking into account the GUI of SAP2000

Thanks for your contributions!
