Silvia,
Thanks for your attention. I meant the program at the bottom of this page: opensees.berkeley.edu/OpenSees/user/tools.php

Frank, Thanks for your suggestion. It works out pretty well. I found that the program OpenSEES post processor you provided online works for my soil-structure interaction simulation. So I want to use it for probably animation or imaging. Do you have an updated version that can be installed in a vista...

Is there a way to output nodal or element information?

I built my nodes and elements using a lot of "for" loops in tcl language. Now i need to check the loops are right and plot the models using another software requiring straightforward nodal and element information. Do you know how to do it? Thank you very much.

Silvia:
Thanks. Sometimes I don't want the program to run the dynamic part, and wish it stops after some basic parameter calculations. Maybe it is not important.
The answer to the second question is very useful. I tried and it worked out. Thank you. :lol:

Breakpoint in opensees?

1. I am wondering whether there is a breakpoint in opensees like in Matlab such that the program would stop at the point? 2. If I want to output some constant numbers and texts to a file instead of "puts" them on the screen, what should I do? I want to track the parameters once I try diffe...

EPP material is the reason for the failure. I changed it to Steel01 and tried LoadControl, and the code works. Now I get into another question. How do I build a rotational spring in a 3D case? Here is my code. # units: kip, inch, sec wipe; model BasicBuilder -ndm 3 -ndf 6; node 1 0 0 0; node 2 0 0 0...

Problem with Rotational spring by using zerolength element

hi, I am building a rotational spring to simulate a hinge. I used EPP material for the spring in which k=200 and theta_y=0.005. The model is built as follows. # units: kip, inch, sec wipe; model BasicBuilder -ndm 2 -ndf 3; node 1 0 0; node 2 0 0; fix 1 1 1 1; set MatTagFlex 1; uniaxialMaterial Elast...

Thanks Silvia. I made a proc to load the file into a list, and it works well. proc EventLength filename { set file [open $filename]; set iDstep [read $file]; set eventlist [list 0]; foreach Dstep $iDstep { lappend eventlist $Dstep; }; set eventNo [llength $eventlist]; return [expr $eventNo-1]; }

How can I get the length of a data vector?

I am a new user of opensees and tcl language. I am wondering how I can automatically get the length of a data vector, for example, an earthquake time history; therefore I can know how many steps to "analyze". Similar commands like last(file) in Matlab and rows(file) in MathCAD? Many thanks.
