Yes, of course ... I'm a structural engineer .... I want to extend TECLA (see the project home

http://sites.google.com/site/teclait/home

to build a FEM software based on SU. Ad the moment I'm developing the Architectural modulus (that will be, with some changes, the Pre_processor).
I'm looking for some FEM software open-source and find some:

Calculix, GmsH, FreeFEM++ but nothing in ruby!!! Someone has news?


i am afraid you won't find anything in Ruby; the language has not been used for structural analysis, as far as i know

but it might not be a problem; you could link a program in Ruby, to another program in another language, by exchanging information through text files

i did it between Ruby and Basic, and it worked...

yes, it could be done.... :D

But, as I'm tryng to develop a FEM engine by myself (I wrote a 2D fem program in MATLAB at University some years ago...), I need a solid matrix/linear algebra library in Ruby. Now the aim is to use it inside SU both in Windows (& Linux+wine) and OSX. I found Matrix.rb but I don't like it ... any suggestion and how use with SU?

I've just started to use SketchUp, but I have a lot of experience in writing FEA code. One thought I had was to link SketchUp with FEMhub which is being developed with a web-based interface so it could be used in a web view via a plugin. They are working on 1D, 2D, and 3D solvers. Their web interface is a bit much for a plug-in, but it's probably a good place to start.

Very interesting idea to have a FEA ruby. I'll be watching to see if anything develops on that front. I sort of agree with the general idea that it may be better to write a translator from SU to an existing FE program, but if it can be done within SU all the better. It does seem like a huge amount of work, though :o

Update: I found (thanks to Google!!) this project

http://frame3dd.sourceforge.net/

released under GPL for Linux (wow!!!), Mac and Windows.
It seems very good...... now I'm asking to the author if Frame3DD supports rigid link to model unaligned elements (colums and beams as in the following image

Was wondering if there's been any development on this.
Through the last post i found the following.

But I'm just not good enough at this sort of thing to get it to work...

Hi guys! I've been away for a while. Anything new in the topic?

I'm trying the Frame3D and found this video of another combination - SketchUp/GoSimulate: https://www.youtube.com/watch?v=kCVoa1u-9BM

Seems like someone made it :)

Edit: Actually no. Should've watched it until the end. So there's still a niche.

"but at least SU could be used as the CAD modeller for GMSH?"
(from a previous post)

The "Meshkit" plugin from Peter V seems to do that.

Did someone try it ?
Because each time I launch SU (SU2015 Make or SU8) I have errors like "Error Loading File C:/Users/PC/AppData/Roaming/SketchUp/SketchUp 2015/SketchUp/Plugins/pv_sketchytetgentools/pv_sketchytetgentools_class_loader.rbe"
etc.

I haven't found any information about this plugin on the forum.
So I post here and hope someone might help with my installation problem.

Cheers.
