Grasshopper components allowing to add properties for structural analysis to Grasshopper geometry and to convert this information to SOFiSTiK input files
Install the components by dragging & dropping the assembly gh_sofistik.gha from the subfolder ./bin onto the Grasshopper window. After installation a SOFiSTiK tab should appear in the control panel of Grasshopper containing four groups of components:
- General: provides a component to start an analysis calculations directly from grasshopper, a component to stream text data to *.dat files or a component to adjust visualization settings globally.
- Section: provides components to create & attribute SOFiSTiK sections from planar geometry, to inspect the sections and to write this information to SOFiSTiK files.
- Structure: provides components to convert points, lines and areas to SOFiSTiK structural elements as well as components to create rigid and elastic couplings between these structural elements. All these structural elements can then be passed to a further component, called SOFiMSHC which converts the structural information into a SOFiSTiK input which can be streamed to a file and calculated there.
- Loads: provides components to add loads to points, lines and areas. As input, Grasshopper geometry as well as structural items defined by the components described before can be used. An additional component, called SOFiLOAD allows to convert these loading items into SOFiLOAD input.
The components for defining structural elements in the structural group also support 'Baking' in a way that the defined analytical properties can be transferred to Rhino being readable by the SOFiSTiK Rhino Interface there. This means, the geometry baked within Rhino can be further edited and meshed to a SOFiSTiK analytical model from there - provided, of course, you have the SOFiSTiK Rhino Interface installed.
Further components with additional functionality, e.g. allowing to define parametric bridge models with varying cross sections or to define pre- and posttensioning tendons will be available in a commercial version.

An online documentation of gh_sofistik is available on the SOFiSTiK webpage: www.sofistik.de/documentation/2020/en/rhino_interface/grasshopper/. The online documentation contains a detailed Command Reference. This reference includes all the components available here + the additional components only available in the commerical version.
An example can be found in the subfolder gh_sofistik/examples:
Please note: the grasshopper assembly is continuously being developed and we cannot guarantee that, e.g. node and parameter names may not change. However these changes mainly take place in the master branch. For productive usage, we recommend to use the version of a specific release, and to download the gha assembly from there.
