Detailed Description

Class IBInterpolantMethod is an implementation of the abstract base class IBStrategy that provides a simple functionality of interpolating and spreading scalar or vector-valued quantities to and from the moving IB structure on the background Cartesian grid.

This class does not provide direct support for fluid-structure interaction, but rather facilitates Eulerian-Lagrangian data management for LMesh.
