DESCRIPTION
Concha is a Rhino3D plug-in for the numerical analysis of shell structures. Based on the Finite Element Method, Concha lets you analyse the mechanical behaviour of complex geometries subject to arbitrary loads without leaving the design environment of Rhino3D.
FEATURES
The key features of Concha are
- Import of any surface-based geometry objects from within Rhino3D
- Specification of supports at vertices, edges or surfaces
- Connection of vertices or surfaces from different geometry parts
- Different material models
- Application of forces to vertices, edges and surfaces
- Temperature and self-weight loading
- Automatised meshing, surface-wise meshing with non-conforming interfaces
- Visualisation of deformed shape, displacement components, reaction forces and equivalent stresses
- No knowledge of Grasshopper or RhinoScript is required
INSTALLATION
Download the installer (MSI for v1.1 or RHI for v2.0) and open by double-clicking. A Wizard will guide you through the installation. Make sure that the system requirements are fulfilled. Otherwise, the plug-in is likely to crash.
SYSTEM REQUIREMENTS
Concha is a plug-in for Rhino 5 SR13 and Rhino 6 for Windows (64-bit). It requires 'Microsoft .NET Framework 4.5.2' and the 'Microsoft Visual C++ Redistributable for Visual Studio 2015-2019 (64bit)'.
FREE VERSION
The free version of Concha (v2.0) has the following limitations
- Linear analysis only
- Reduced number of material models
- Maximally allowed number of finite elements is 2000
FULL VERSION
A full featured version of Concha (v1.1) for Rhino 5 can be purchased here. Student and commercial licenses are available.
