Use the Planar Slip tool to constrain surface mesh on planar faces. Mesh on selected surfaces will only be allowed to slip tangentially
along the planar surface.
Use the Free Surface tool to specify free surfaces and impose the appropriate nodal boundary condition on the mesh motion on those surfaces.
Free surface properties are defined by surface tension and contact angle parameters.
Use the Interface Surface tool to define an interface for moving mesh. Optionally, this tool allows you to define
topological baffle surfaces as an interface surface.
