Deforming an edge in Deformed Geometry Interface in 3D model.

Hi All,

We are working on a comsol model with Solid Mechanics and Deformed Geometry interfaces.

In our 3D model, we are using Prescribed Normal Mesh Velocity and Prescribed Mesh Displacement to assign required deformation in the domain. In 3D models, these both interfaces are applicable to a particular face only and not on any edges.
Is it possible to apply, a prescribed mesh displacement along an edge (not on a face) in 3D, using weak constraint or Pointwise Constraint or in any other way.

Thanks in advance. Regards. A. P.
