What version of matplotlib you are using? I use matplotlib ver. 3.3.4 and it works. set_box_aspect option has been added to matplotlib 3.3, so you need at least this version to make it work. https://matplotlib.org/stable/users/prev_whats_new/whats_new_3.3.0.html#axes3d-no-longer-distorts-the-3d-plot...

The specified scaling factor (80) is too large for this model and load. Remove it from first plot_defo argument and then adjust. If not specified, the scaling factor is calculated automatically based on the model geometry. The maximum displacement shown on the plot is 20% of the maximum model size. ...

I don't use it, but look here:

I found by accident github repository for OpenSees

Jhno,
According to the documentation of tcl
http://wiki.tcl.tk/1476
by default the optional parameter ?increment? is equal to 1, so
"incr i 1" is eqivalent to "incr i"

I tried another model available from the following webpage: Implementation of a Simple Biaxial Concrete Model for Reinforced Concrete Membranes by Bernardo Garcia Ramirez https://era.library.ualberta.ca/files/cdj52w5112/Garcia%20Ramirez_Bernardo_201709_MSc.pdf This is Mazars Damage 2d model, the Ope...

I'm also interested: rafallo8791@gmail.com
Thank you in advance!

You can use 'parameter' and 'updateParameter' OpenSees commands. See the docs for the syntax. You can use this approach when the materials of interests have setParameter method in cpp source files. From OpenSees/SRC/material/nD/UWmaterials/DruckerPrager.cpp we have: ---------------------------------...

Thank you for hints. I tried various optimization flags when compiling recent Opensees (svn 6602) and the results are as follows: Analysis execution time: 393 seconds - Windows 7, downloaded 2.5 version Analysis execution time: 575 seconds - compiled with -Ofast Analysis execution time: 964 second -...

Thank you Frank! The new svn 6598 commit fixes the problem.

I noticed a significant difference in execution time when running 'slopeAnalysis2Deff.tcl' (which requires velocityHistory.out) downloaded from [1] on the same computer but two operating systems. Namely under Windows the execution time is more than three times faster than on Linux Debian 9. On windo...

I would like to inform you that under Debian, there is a new Build Error caused by svn commit 6590 X.Zeng - update. ExplicitDifference.o file is not built due to compile errors. UPDATE: To be more specific the issue is due to changes in ExplicitDifference.cpp and ExplicitDifference.h files. I think ...

I would also be interested in using Damage2p material, however this material is available nor in the sources nor in the Windows executable files provided on the Opensees website. Is there a previous version of Opensees which was compiled with the Damage2p code? Thanks in advance.

Dear Frank, The video and presentation from the Opensees days 2012 by Quang Gu on SNOPT Optimization features in Opensees is very interesting, however there is no documentation and no examples on Opensees wiki page. What is the status of SNOPT in Opensees: is it compiled in executable files? What ab...
