NodeSelector

Which nodes of a mesh a load acts on, as data (node-workers §NWI-10, construct-fea-solve §FEJ-1).

In the namespace femjob. Declared in src/libs/libfemjob/femjob/LoadCase.hpp.

Detailed description

A load case written before the mesh exists names nodes by where they are: a box, a plane, or the band at one end of an axis. The band is the usual way to say "the bottom" of a part whose exact size the mesher decided. Positions are in the frame the solve runs in: after the load case's `transform`.

A load case written for one mesh, as Construct writes it from its regions, names them by index: `nodes`, a node set, or `faces`, boundary triangles wound outward. Each carries the region's `name`, so a failure names the region and not the load's place in the list.
