Amazon EC2
Is regular Opensees (not SP or MP) available in Amazon EC2?

Re: Problem with ModIMKPeakOriented and ModIMKPinching mater
Also, ModIMKPeakOriented and ModIMKPinching materials will make the model run very very slowly. But Bilin materials won't.
Has anyone fixed the problem yet?

Please upload webinar material
Dr McKenna,
Can you upload the pdf for the webinar "How to Build a Model of a Structure Faster with a Script than with a GUI" on June 12?
Thanks!

2 story braced frame pushover
Hi, I'm having some problems in the pushover analysis of a one-bay two-story braced frame. My code is based on Dr Terzic's script in the discovering Opensees seminar (http://opensees.berkeley.edu/wiki/index.php/Discovering_OpenSees_--_Modeling_SCB_frames_using_beam-column_elements). I just add anoth...

simultaneous use of equalDOF and rigidDiaphragm constraints
Hi all, I find some issues about using equalDOF and rigidDiaphragm constraint at the same time. I suspect there are some bugs going on. The issues arises when I'm trying to modeling 3D braced frame. But here, for simplicity, I'll take out only one bay for illustration. Numbering and configuration of...

Re: problem in uniaxial material in series
Dear Dr. Terzic, Thanks you very much for your reply! I have some follow up questions. So basically you made 2 changes to my previous code: 1. apply sp at the dof1 at node 2 instead of load 2. use Penalty Constraints instead of Transformation 1st question You said the structure in my previous is uns...

Re: problem in uniaxial material in series
I think this is a very series bug! Any one has any idea?

problem in uniaxial material in series
Hi, I'm just trying to assign a material which consists of 2 uniaxial elastic material in series to a truss element. The truss element is simply supported and I applied an axial force at the roller but the analysis fails. It says my matrix is singular. Surprisingly, if I just change those 2 material...

Re: running opensees in Neeshub
Thanks for your reply,
My model is 3-D and has almost 3000 nodes. Is it applicable to parallel computing?
Thanks!

running opensees in Neeshub
Hi,
I tried to run a time history analysis of a large model of opensees model in Opensees Lab NEEShub. But it turns out that it took almost as much time as it did on the desktop in my office ( around 4 hr). Why is that?
Is running opensees in NEEShub parallel processing at all?
Thanks!

Re: weird result in eigenvalue analysis
Hi all, I think I find part of reason to the problem. The model that is creating the problem is nonlinear and the result of eigenvalue analysis depends on where you put the command. If you put the command of eigenvalue analysis right after you build the model (without applying any load), the program...

weird result in eigenvalue analysis
Hi all, I'm having some weird result in eigenvalue analysis of a 3-D 2-story shear building (with rigid diaphragm). I use the command eigen -fulGenLapack to get the eigenvalue of the structure. I'm analyzing the same model. For the first time, I use eigen -fullGenLapack 6, which gives me the first 6...
