OpenSees, the Open System for Earthquake Engineering Simulation

Recently I wanted to put opensees binary as ppa in ubuntu launchpad but it's not possible because you can only add FREE software. We must find a place which allows both free and proprietary software. The second option is an interesting repo on github (if you search you will find it) which has Docker for opensees ver 2.5 (not continued). And the third option is an appimage like FreeCAD.

requires GLIBC_2.29 but buster has 2.28-10 means it probably runs on Debian Testing aka Debian bullseye

I thought you have Ubuntu. I will try to compile it on Debian too as soon as I can.

Debian Buster is what I am on. If you are able to compile OpenSees on debian Buster, it would be good if you could post the steps and the packages needed to do.

I wrote a bash script which works both for Debian and Ubuntu to download and compile Opensees. Here is the link to bash script:

Please send me feedback for the above bash script. And if you want to download directly the binary file of Opensees here is the link:

works great on Debian Buster

direct .tcl file link

if I run this file in OpenSees I get ...

Code: Select all

    while executing
"recorder plot Node.out CenterNodeDisp 625 10 625 450 -columns 1 2"
    (file "Example8.1.tcl" line 90)
hugo@Ahorn:~/bin$ 

and an empty file Node.out as well as a 10.0 MegaByte file gmon.out is created. -1 seams something went wrong ?

There is a basic truss example on the following page. In my opinion its another good starting point alongside Ebrahim cantilever code.

A little bit off topic but studying the documents of fem workbench, I see it is hugely relied on c++ codes. Or maybe I should learn more.

It is a mix of C++ and Python. It depends what the aim is. A lot can be done with Python, really a lot. For example to implement a new solver only less than ten lines of code need to be C++ where as all other code can be Python. Only a few things can only be done in C++. As said it depends.

But if one would like to do C++, most things could also be done in C++. All this is for history reasons.

Thanks for the example. I will give this one a try and see if it fits better.

cheers Bernd

Is it possible to output results in vtk format?
