The Magnetomechanics, Membrane interface (
), found under the
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 Membrane and Magnetic Fields with a moving mesh functionality to model the deformation of magnetically actuated membranes. The
Magnetomechanics, Membrane interface is available for 3D and axisymmetric 2D geometries.
When this multiphysics interface is added using the Model Wizard, a
Membrane interface and an
Magnetic Fields interfaces are added to the
Model Builder. In addition, the
Multiphysics Couplings node is added, which automatically includes the multiphysics coupling feature
Magnetomechanics, Boundary.
The full functionality of the Membrane and Magnetic Fields interfaces is accessible under the corresponding interfaces at the domain, boundary line, or point level in the geometry. The participating Magnetic Fields interface by default adds the
Free Space node with its selection set to all domains. This node serves to represent dielectric domains adjacent to the shell domains. Any number of
Ampère’s Law in Solids or
Ampère’s Law in Fluids nodes can be added manually to the interface to represent either solid or nonsolid materials.
