The Magnetomechanics, No Currents interface (
), found under
Electromagnetics–Structure Interaction (
) branch within the
Structural Mechanics branch (
) or the
Electromagnetics and Mechanics (
) branch within the
AC/DC branch (
) when adding a physics interface, combines
Solid Mechanics and
Magnetic Fields, No Currents interfaces with a moving mesh functionality to model the deformation of magnetostatically actuated structures. The interface is suitable in cases when induction and conduction effects such as eddy currents are negligible within the structure.
The Magnetomechanics, No Currents interface is available for 3D, planar 2D, and axisymmetric 2D geometries. When this multiphysics interface is added using the
Model Wizard, a
Solid Mechanics interface and a
Magnetic Fields, No Currents interface are added to the
Model Builder.
In addition, the Multiphysics Couplings node is added, which automatically includes the multiphysics coupling feature
Magnetomechanics.
The full functionality of the Solid Mechanics and Magnetic Fields, No Currents interfaces is accessible under the respective interfaces at the domain, boundary, edge, or point level in the geometry. The participating Magnetic Fields, No Currents interface by default adds the
Magnetic Flux Conservation in Solids node with its selection set to all domains. This node serves to represent solid magnetic material domains. Any number of
Magnetic Flux Conservation in Solids or
Magnetic Flux Conservation in Fluids nodes can be added manually to the interface and configured to represent either solid or fluid materials.
