A few pre/postprocessing tools are already available for OpenSees and make life easier regarding its cumbersome text-only environment. However, all these tools are problem-specific and can handle a limited range of engineering applications.
The new GiD+OpenSees Interface is bypassing all these limitations, taking advantage of the excellent general pre/postprocessor GiD, where practically anything can be graphically modeled with ease; from simple plane and space trusses and frames to complex hybrid 1D/2D/3D element models. The interface seamlessly translates the model geometry/properties into input code, executes the analysis and forwards all results to the graphical postprocessor.
Since the evaluation version of GiD comes with a generous 1010-node limitation, the majority of frame models (e.g. buildings/bridges) and a few 2D/3D models can be modeled for free. For more complex and dense geometry, a GiD license is required. Nonetheless, all provided tutorials and examples in this site can be tested using the GiD evaluation version.
The GiD+OpenSees interface is open source and will remain that way. The current state of development provides a comprehensive set of materials and 1D/2D/3D elements for linear / nonlinear static and dynamic analysis, as well as supporting multiple model domains for easy modeling of SSI problems.
If you think that this tool is useful, you can provide feedback and/or contribute your own code (new materials/elements etc.) to the repository. For covering administration costs and keep the project active and running, a small donation is greatly welcome in the provided link alongside.
