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 and open by double-clicking. A Windows installation wizard will guide you through the installation. 

SYSTEM REQUIREMENTS

Concha is a plug-in for Rhino 5 SR13 for Windows (64-bit). It requires 'Microsoft .NET Framework 4.5.1' and the 'Visual C++ Redistributable for Visual Studio 2015 (64bit)'.

FREE VERSION

The free version of Concha has the following limitations

  • Linear analysis only
  • Reduced number of material models
  • Maximally allowed number of finite elements is 2000
