Hello,
The math does not render on the OpenSees wiki anymore.
Please fix so that it is readable.

Re: convergence of analysis
The return code from the analyze command can be used in the IDA to designate failed runs. Often it is done in this way:
set ok [analyze 1]
Then, at the end of the analysis, you can write the return code to a file:
set fid [open code.out w]
puts $fid $ok
close $fid
set ok [analyze 1]
Then, at the end of the analysis, you can write the return code to a file:
set fid [open code.out w]
puts $fid $ok
close $fid

Re: zerolength, damping and natural frequency
Try [eigen -fullGenLapack 1]. You only have 1 mass, so the generic eigen solver won't work.

Re: BRBF model using OpenSees
Hello, I would look at Santiago Zaruma's Thesis: Seismic stability of buckling-restrained braced frames, and Ozgur Atlayan's Dissertation: Hybrid Steel Frames for information on this. From what I have seen and done, you are going to want to use beam-column elements for the frame (P-Delta for vertica...

Incomplete documentation on beam element recorders: force, localForce, globalForce
Hello, It is not clear what to do for beam recorders and what the different columns in output are. On the main wiki (https://opensees.berkeley.edu/wiki/index.php/Elastic_Beam_Column_Element), it states to use the query "force". However, this gives the global force in my experience. Contrar...

OpenSees wiki not showing math symbols.
It seems the math interpreter is broken on the OpenSees command manual wiki. I pulled up a cached version of the site on my browser, so I am quite confident it is not on my end.

I am struggling to understand the documentation for the Rayleigh command. These are the inputs to the Rayleigh command: $alphaM factor applied to elements or nodes mass matrix $betaK factor applied to elements current stiffness matrix. $betaKinit factor applied to elements initial stiffness matrix. ...

OpenSees in Notepad++
Hello all, Editing Tcl files for OpenSees is not well supported by standard text editors, and the text editors that do support it are not robust (such as Cypress Editor). So, I combined the functionality of Notepad++ with the OpenSees language support of Cypress Editor. The code is located at https:...

Re: A display window disappears immediately. An urgent solut
Hi jjh,
Try adding this code at the end of your analysis:
puts "Press a key to continue"
gets stdin my_variable_name
It will prevent the screen from closing until a key is pressed.
