Re: Mismatch on portal deformation

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. ...

Re: Why my dynamic analysis does not continue until degradat

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"

Re: Update

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: ---------------------------------...

Opensees under Linux (Debian 9) slower than on Windows 7

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 ...

Re: nDMaterial suitable for concrete block

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.

What is the status of SNOPT in Opensees: is it compiled in executable files? What ab...
