Three-dimensional surface mesh (.smesh) files
Surface mesh files may also be specified in the form of a surface
triangulation. This is particularly convenient when the surface mesh
is created by some other piece of software.3.1 File format for surface triangulation input can be summarized using
a pseudo-template file (see Section 3.2), where
nsurfs is the number of disconnected closed surfaces.
Note that this format is hard-coded, and not a true template. Also,
multi-domain geometries can not be input using .smesh files,
because the file format is not expressive enough to allow non-manifold
surface meshes. Geometry input will be rewritten at some point in
the future to allow easier extensibility to new geometry types; when
this happens, support for the .smesh file format may vanish,
so new input files should use the .bdry format.
