The OpenSees Community

Thanks, Frank. This really helps. There is one file, entitled "Introduction to Parallel Computing ", not downloadable. There might be something worng in the link. Stan [quote="fmk"]the materials are available at [url] http://opensees.berkeley.edu/OpenSees/workshops/parallel09/Age...

Frank/Silva:

Can I still have a good chance to look at the materials for the May 2009 workshop on the parallel OpenSees that were once posted on line? The link does not work anymore.

Thanks,

Stan

I had two problems in pushover analysis for a column. This column is modeled in 2d and 3D. In 2D plastic pushover, it looked normal. But in 3D pushover, there was axial stretching during the pushover analysis. By saying axial stretching, I meant the free end of the column had axial extension instead...

This is a very good point. I will change it later. Yes, I am having some convergence problems when the drift ratio exceeds 4%. So usually I only push upto 2.5%. also, you are doing test NormDispIncr 1.0e-8 100 0 with 100 iterations. if newton doesn't converge in 6, you should try something else. are...

I am doing the fragility analysis that requires pushover analysis for the entire structure during each interation. So the speednecking is the pushover analysis on the structure. My bridge model has 22 nonlinear beam columns with springs at the bottom of each column. EAch column only has one element ...

Steel01. Sorry I gforgot to mention that.

I am using concrete02, nonlinear beam column element with fiber section.

So, what kind of solver would you suggest to use instead. here is the script: constraints Plain system ProfileSPD numberer RCM test NormDispIncr 1.0e-8 100 0 algorithm Newton integrator LoadControl 0.1 1 0.1 0.1 #initialize analysis Static if {$PUSHOVER == "DispControl"} { set dU 0.1; # Di...

Besides increasing the dU, any other choice to speed up the pushover analysis maintaining the same accuracy?
Thanks.

Thanks, silvia. I am not sure on your saying "set up the elements in parallel". Because of the integrator command, I was thinking that for each sectional analysis/pushover analysis on one section/structural member, we need a reference node for the analysis on each section/structural member...

Hey, all I am trying to include the sectional analyses/pushover alalyses in one openSees run. Because these analyses require "integrator DisplacementControl". So my question is whether it is possible to include multiple "integrator DisplacementControl" commands such that I can do...

Frank, I found the difference between your debugging and mine. Please help me understand on "settting the BP at the method". The only way I know in setting the BP is using F9 inline. Thanks. are you sure you are even getting to the method you are having the problem with .. when i played wi...

Thanks for your quick reply, frank. I did use F5 for the start of debugging. The BP was still non-stoppable. I was able to get into tclMain.cpp in project openSees , and commands.cpp in project tcl by the way. But the code code = Tcl_RecordAndEvalObj(interp, commandPtr, 0) in tclMain.cpp prevented m...

Hey, I am trying to stop at one of the OpenSees projects, say at the cpp file " NatafProbabilityTransformation.cpp" line 596 in project reliability>transformation, by F9 setting Break Point at the first line of "if (rv1Ptr->getMean() == 0.0 || rv2Ptr->getMean() == 0.0 ) { opserr << &q...

Thanks, Frank. Things are really weird. Before I read your message. I couldn't debug although I followed the same procedures. But after you posted the reply, things got perfect as I expected. Is it God helping me or was I debugging a different cpp file that would never be reached for the tcl file I ...
