[Libmesh-users] normal vectors on surface meshes

[Griffith, B. E. <bo...@em...>]

Folks --

Is there an easy way in the library to get normal vectors on surface meshes (e.g. 2D elements in 3D space, 1D elements in 2D space, etc)?  It seems like most of the support for this assumes that these are only needed for doing surface integrals on volumetric meshes, but I am sure I am overlooking something.

(Of course, I know I can do this "by hand" if needed.)

Thanks!
