OpenSees, the Open System for Earthquake Engineering Simulation

[bernd]

very thanks.

1- for GUI, i agree with you and i wanted to describe the hardness of Gui part!
2- for whole concrete structure i use beamcolumn element in opensees (like common analysis softwares) that is 2D element. but with sections we can define a mesh area with patch and add rebars with layer. this pdf can explain more:

http://opensees.berkeley.edu/workshop/O ... ug2003.pdf

for common engineering purpose we don't need mesh generation at all. only for shear wall we must generate mesh. i will study for shear wall more.

how about the slabs?

Hello,

I found these link/documents.

https://openseespydoc.readthedocs.io/en/latest/
https://buildmedia.readthedocs.org/medi ... spydoc.pdf
http://www.joseabell.com/opensees-coming-to-python.html

The manual is complete with procedures and examples.

Is there the possibility to install Openseespy in FC with pip command without installing the full Anaconda Package?

With Opensees FEM workbench would be complete with tools for earthquake analysis....Structural engineers would like that (there are many options like pushover analysis, concrete section defined as fibers, and more)...

About slabs I think that opensees is integrated with quadrilateral elements (shells). It is a chapter dedicated in the manual (see second link)....

you can install extra package with pip install command. and about mesh, i agree with you, opensees have complete command for mesh generation in it's command. only thing is, that we need a gui to draw sturcture in it and then produce opensees input file from Gui and analyse it with opensees.

What mesh input and result output format does OpenSees uses?

All the best Bernd

now I understand your point for mesh format @bernd

as i know, opensees did not support any mesh format, but there is a library in python that parse gmsh .msh format for it:

opensees has its own mesh generation internally, for example:

https://opensees.berkeley.edu/wiki/inde ... 3D_Command

and this are elements:

Dear Mr @bernd:

I have been searching to implement opensees in FreeCAD for a while. In one of the posts I saw you are looking for a binary of opensees for ubuntu. I think I can provide you the binary file. Also I made a video to instruct how to compile opensees in centOS but unfortunately it's in persian. Besides that I'm very interested in cooprate with implementing opensees solver in freecad...

Thank you @shahram10715, it's interesting that also you are looking for this. me and shahram are Iranian.

Yes, it's interesting to see the ways open source and engineering attracts different people. very cool.
