Accessing Frame3DD within FreeCAD
Frame3DD is free open-source software for static and dynamic structural analysis of 2D and 3D frames and trusses with elastic and geometric stiffness. It computes the static deflections, reactions, internal element forces, natural frequencies, mode shapes and modal participation factors of two- and three- dimensional elastic structures using direct stiffness and mass assembly. Frame3DD has its own text-file input format (.3dd), but additionally supports matlab (.m) and spreadsheet (.csv) file formats, and offers graphical output including mode shape animation via Gnuplot
FreeCAD is an open source CAD/CAM solution.
Currently this workbench contains the following tools:
The ability to read in an 3DD case file. It also copies said 3DD file into FreeCad's bin/ folder and renames it as hfcFrame3DD.3DD.
Not implemented yet.
Output a new 3DD file when user makes some change to the model or load.
Execute the Frame3DD binary which reads in the hfcFrame3DD.3DD file and writes the result into the hfcFrame3DD.txt file (within FreeCad's bin/ folder).
Read in the hfcFrame3DD.txt file and draw the mesh and displacement.
- Frame3DD v
- FreeCAD v0.19.x
This workbench is developed on Windows 10.
Note: Frame3DD excutable file must be located at FreeCad's bin/ folder. Under Window 10, it is named Frame3DD.exe . Under Linux. it is named 'Frame3DD' .
Download as hFrame3DD.zip and unzip it under FreeCad's Mod/ folder. The result is a new 'Mod/hFrame3DD' folder with all the codes.
Feedback, discussion, and any participation can be done through the dedicated FreeCAD forum thread
