Re: SAP2000 vs. OpenSees Pushover Curve
For large structures, since there are only a few large-scale tests that have been done, the validation of the numerical response should be done at a component level. Then you should get back to some engineering fundamentals to check global and local responses. For component validation, there is a lo...

Re: Tapered Beam
For modeling a tapered beam, you can use the forceBeamColumn element and assign different sections to the element using the "-sections $secTag1 $secTag2...". You will need to assign a different section for each integration point along the element. Please have a look at: http://opensees.ber...

Element local forces XML header typo
Hi Frank, There seems to be a very small typo in the ElementOutput header. I think the sixth ResponseType should be Mz_1? <?xml version="1.0" encoding="UTF-8"?> <OpenSees xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation = "http:...

Re: Redirecting stdout and stderr for each $pid
Thanks Frank. Would something like is described in the following link work? Would OpenSeesMP have to be compiled with mpich2? h***://wiki.mcs.anl.gov/mpich2/index.php/Hydra_Output_Redirection For now, I tried the following "mpiexec -l -np 3 OpenSeesMP runAll.tcl > logFile.out 2>&1" whe...

Re: Requesting absAccel/absVel/absDisp
Maybe what may be useful is something like the following command to output absolute accelerations (velocities and displacements, also) in X, Y and Z, for example:
recorder Node -file output.out -timeSeries $IDloadTagX $IDloadTagY $IDloadTagZ -time -node 1 -dof 1 2 3 accel
Thanks
recorder Node -file output.out -timeSeries $IDloadTagX $IDloadTagY $IDloadTagZ -time -node 1 -dof 1 2 3 accel
Thanks

Redirecting stdout and stderr for each $pid
Hi, How can I redirect stdout and stderr for the process running in a $pid to a different file (see example below)? I tried the following command that outputs all stdout and stderr from all $pid to the same logFile: mpiexec -np 3 OpenSeesMP runAll.tcl > logFile.out 2>&1 Thank you Andre *********...

I agree. Why don't you add it to future requests?

Re: patternUniform excitation and timeSeries
Thank you for the reply. I had also reached that conclusion that for now it does not seem to be possible, but by trying out on a cantilever SDOF. In an effort to reduce the number of recorders for a big structure, it might be worth adding an option that for a 3D case could look something like "...

Re: patternUniform excitation and timeSeries
Thank you for the reply. It worked well. One more question. Would the format be the one I have in the next line if I want to use one recorder to output the absolute acceleration in more than one direction, for example X and Y? recorder Node -file output.out -timeSeries $IDloadTagX $IDloadTagY -time ...

Re: Eigen analysis
By the way, it might be worth changing the very nice and clear example of the eigen analysis shown available in: http://opensees.berkeley.edu/wiki/index ... hear_frame
Thanks again for the good job.

patternUniform excitation and timeSeries
Hello, If I wanted to define the UniformExcitation using timeSeries so that I could get the absolute nodal acceleration directly using a recorder, can my commands look like the following? timeSeries Path $IDloadTag -dt $dt -filePath $outFile -factor $GMfact pattern UniformExcitation $IDloadTag $GMdi...

Eigen analysis
Dear All,
I realize the eigenvalues are computed when we set the [eigen $numModes] command without using the analyze command. Is it also possible to output the eigenvectors without invoking the analyze command? If not, I would like to understand why not?
Thank you
