GSA-Grasshopper release notes
Build 1.4.0
July 2024
GSA-Grasshopper 1.4.0 allow adding static P-delta analysis task and includes smaller bugfixes.
Features

Build 1.1.0
December 2023
GSA-Grasshopper 1.1.0 introduces spring properties and includes refactored results with speed improvements and the ability to get Max/Min.
Features
- New CreateSpringProperty and GetSpringProperty components
- Ability to set/get spring properties through Edit Node, Edit 1D Element and Edit 1D Member components
- All Result components can return Max/Min envelope values.
- Improved speed of result components using direct methods in the API.
- New Element 1D Stress result components for both derived (Von Mises) and normal stress results).
- Improved Footfall results does not use COM and expose more result subsets, as velocity and frequency.
- Result diagrams component can display Member results.
- New components to work with 1D Members' Effective Length Options
- New Expand Beam to Shell component which will convert most commonly used (open) profiles from a 1D Element or Member into 2D Members
Fixes
- Contour 1D results for a Combination Case of 1D Element Displacements are previously wrongly displayed in local axis, corrected to be transformed to global axis.
- Select Result component Issue of crashing when toggling between Analysis and Combination Case with a CaseID that does not exist has been solved.
- Edit 2D Element's topology output returns the entire list of node IDs instead of only the first two.
Build 1.0.0
October 2023
Official release of GSA-Grasshopper plugin following an extended period of beta testing.
Features
The GSA plugin enables computational design and automated workflows for structural engineers, utilising the powerful geometry engine in Rhino and the low-entry, visual scripting of Grasshopper.
Run GSA headless through the .NET API
- Run GSA.Inside.Grasshopper - and potentially extended to any program that can run Rhino.Inside.
- Fast and responsive, utilising the speed of GSA's solver for real-time feedback.
- No more interoperability; you are literally running GSA inside Rhino's process.
Work with existing files
- Not all team members required to know how to use Grasshopper.
- Share GSA files (.gwb) created parametrically in Grasshopper with colleagues for checking or further work.
- Open existing GSA files (.gwb) inside Grasshopper.
Native Rhino/Grasshopper Geometry support
- Use all built-in Grasshopper components for geometry transformations, including: move, mirror, morph, array, twist, offset, etc.
- GSA-Grasshopper's custom parameters will convert (or cast) automatically to or from native Grasshopper parameters.
- It is possible to "Bake" all GSA-Grasshopper parameters into Rhino
- Additionally, you can preview 3D sections, applied loads and result diagrams from GSA inside Rhino.
Meshing
- Utilise GSA's powerful meshing capabilities inside Grasshopper; GSA-Grasshopper uses one of the fastest and most robust FE meshing algorithms on the market.
- Create your geometry using Members and let GSA manage intersections and the creation of the analytical model.
3D Sections
- Preview 3D sections of the GSA model inside Rhino
Results
- Visualise results within Rhino/Grasshopper to check your design, or use it to automate your engineering workflow.
- Use GSA's powerful post-processing tools to create and retrieve results for load combinations.
- Load and result diagrams and their values can be displayed and annotated directly in Rhino's viewport.
Easy handling of units
- All components and parameters are underpinned by units.
- Convert to and from any relevant engineering units.
- Based on opensource UnitsNet, and extended with engineering units by Oasys.
Fixes
- All reported and known issues from the beta testing period have been resolved.
General
- The plugin is distributed through Rhino Package Manager.
- Rhino 6.27 or later is supported.
- GSA-Grasshopper requires GSA 10.2 to run.
