Abstract
In this paper, we introduce a Lagrangian approach for 3D electrostatic analysis. In this approach, when the conductors undergo
deformation or shape changes, the surface charge densities on the deformed conductors can be computed without updating the geometry of
the conductors. This alleviates the computation-intensive task of remeshing the structure and regeneration of shape functions.
