The OpenSees Community

Hello
could someone explain me how to connect elements
The command geomTransf in space
the thing is that i don't understand the indications XZ plane etc
for example, i have analysed a simple 3d frame, but when i review the forces it states that a beam has end values of 0 in MZ and Vy, clearly this is not true beacause it is fixed

HELP

great
thanks selimguay

Good advice, thanks selimgunay

i fully understand selimgunay

it is a lot of work to do, i would like a way that open sees fully displays the diagrams or generates a file with data in order to plot the diagrams

hello

currently, like you mohsenrock i'm wondering how to plot the diagrams? i mean how do i figure what is going on at the middle of a beam?

Hello
does anyone have data or a paper that could share with me of a shaking table test concrete frame one story?
i mean i need the experimental results, so that i can construct my model in opensees and after the simulation a comparison would be donde
i need real data, a simple frame
please help me
even if it is steel or concrete
thanks opensees community

zak and selim
i have downloaded opensees navigator, now i can visualize my models

thanks all of you for supporting me
we will continue to make this community bigger

For this code, now i have tried with an editor called Cypres Editor, thus this is the code for the display

############################################
# Display the model

recorder display "Model000" 10 10 600 600 -wipe
prp 0 0 50
vup 0 1 0
vpn 0 0 1
display 1 2 10

set ViewScale 5;

is there an error? when i run it in cypress editor, it unfolds the results of open sees and for a brief instant my model is shown
how can the model displayed stays in the screen?

Thanks both of you
i have downloaded the program os lite, it has several template, however when i introduce my code the first time it runs well, but the model is not displayed. Then in a second run the os lite program fails
here is my code, it works well on open sees, displacements and reactions are verified with staad pro

i don't know how to attach a screenshot
please help me, the example file is confusing me (The example of opensees with the sections)
how can i view my model displayed]??

Halloa world

In order to begin, i am new to opensees, it is fantastic.
How can i visualize my model in opensees, for example i have a small 2D frame, the analysis is only static; you know light.
my results are correct (Verified with staad pro), displacements, etc.
is there a way to "view" my frame or my models
after all, i know that a recorder called display exists, but i don't know how to use it, well i tried but the program told me that the eigenvalues needed to be defined first. Obviously i don't want that analysis, i'm starting wiht the basics (Undergraduate student)

Come on

Gabriel

Thanks Edward and Selim, after some trials i just restarted my PC and it worked

hi, i have downloaded open sees, actually i don't have any experience in programming.
the installation and running of open sees and tcl is perfect in my pc, but please could you tell how can i write file with the extension .tcl or where do i write the programs
i mean i don't want to work every time in the system symbol cmd
once i did programs on c++ with an application that showed me the errors and compilated the program
or should i use the memo pad of windows
please help i don't know what to do, the information is so confusing to me
