This will allow Frame3DD results to be visualised using OpenGL graphics, as well as allowing us to validate Frame3DD in comparison with commercial tools that support this file format. We propose next to implement support for converting between Frame3DD input files and Microstran. This has already proven to be a useful tool, even without structural analysis capabilities. ExampleĪs a first step to implementing basic interoperability between Frame3DD and other structural analysis programs, we have implemented a parser and viewer that reads Microstran ".ARC" files and displays them in 3D.

Click below to see formatted and commented input data, the associated output data,Īs well as plot and movie outputs generated using the program. The following input data files are included with the Frame3DD download packages. Currently, we are able to load and view exported Microstran models, and we plan to incorporate ".ARC" as an alternative input format.įrame3DD is licensed under the GNU General Public Licenseĭocumentation, examples, source code, and the binary program for your operating system. Included in the program is a parser for Microstran. The source code includes: frame analysis, LDL' decomposition, LU decomposition, Newton-Raphson iteration, sub-space iteration, Stodola iteration, Sturm eigenvalue check, static condensation, Guyan reduction, and dynamic condensation. It computes the static deflections, reactions, internal element forces, natural frequencies, mode shapesĪnd modal participation factors of two- and three- dimensional elastic structures using direct stiffness and mass assembly.įrame3DD 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 version 4.6.

Frame3DD is free open-source software for static and dynamic structural analysis of 2D and 3D frames and trusses with elastic and geometric stiffness.
