hFrame3DDfc - Frame design with Frame3DD in FC

[thschrader]

In your drawing, some elements are colored in Red and some in Blue. What it means? Element in Compression or in Tensil ?

blue=tension (see index t in frame3d result file)
red=compression (index c in ...)
The symbol at the fixing with the 6 little squares means all 6 degrees of freedom (3x force, 3x momentum) are fixed.
done with software from pcae:

just a thought: I will try to use paraview for displaying result-graphics.

There is a parameter "x-axis-increment" in the 3dd input file, which subdivides all beams.
The result is written in the if01 output file. (here: beam 15, length 3 m, subdivide every 100 mm).
idea: export the frame from FC, import in paraview and use if01-data to project it on the
frame members for visualization. Numerical result in N*mm for momentum, divide it by 1 million to get kNm.

Yes, I noticed this dx. I think I can read the if* files.

The 6 dots For 6 dof is interesting.

Looks good!

I played a little bit with spreadsheet.
Load file, export spreadsheet as input.3DD file.
Start new document in FC, start frame3D-wb, load input.3DD, run analysis.

Frame3DD has a spreadsheet interface here:

I haven't tried.

What do you think?
Frame3D versus Nastran.

Frame3D is dedicated to 1d elements and has non-linear ability. Nastran95/Mystran has more, like 2d shell elements, though a bit old.

I am only a hobbyist but this subject is of particular interest to me however my operating system is Linux. My question is can this concept be integrated into a Linux operating system?

You could compile Frame3DD from source under Linux or use XCFEM mentioned here https://forum.freecadweb.org/viewtopic. ... 68#p511902

Then let the WB know where you installed it and the name of the executable file.
