High-performance multiphysics FEM simulations in the Sparselizard open source library

Sep 23, 2021, 1:15 PM



This talk demonstrates the capabilities of the open source FEM library Sparselizard
( through mini-examples focused on the physics of interest for particle
accelerator magnets. The equations and simulations are set up on the 3D geometry of
CERN’s Feather M2 particle accelerator magnet for the following physics:
 DC electric current flow through the magnet conductor
 Static magnetic field including saturation in the iron yoke
 Mechanical deformation due to the magnetic field forces
 Multiphysic simulation of a quench propagation in the magnet combined with
conformal adaptive mesh refinement and interpolation order adaptivity (hp-FEM)
 Large scale acoustic wave propagation through the magnet with a high performance
domain decomposition algorithm running on a supercomputer
Because using the Sparselizard library leads to a very compact and concise code the miniexamples
can all be described in details down to every single line of code. All mini-examples
will be provided online.
