Lenz's Law via 3d FEM/BEM coupling -- Magnet dropped down a copper pipe. This is a simulation of a classic experiment that demonstrates the principle of eddy current brakes. With our FEM/BEM coupling scheme no re-meshing has to be executed when the magnet falls through the pipe. A full resolution animation can be found at: http://tailsit.com/lenz/lenz.gif

TAILSIT extended its electromagnetic solver in order to tackle eddy-current problems with FEM-BEM coupling. The application uses the Finite Element Method (FEM) for the solid parts and the Boundary Element Method (BEM) for the exterior domain. To accelerate the FEM-BEM coupling the Fast Multipole Method (FMM) and Algebraic Multigrid (AMG/AMS) are used.

The results for Compumag's TEAM 7 problem show excellent agreement with measured reference data. More info can be found here: http://www.tailsit.com/publications/team7.pdf

We have released the initial version of Concha, 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.

Concha is available from food4Rhino (http://www.food4rhino.com/app/concha).
