LoadEntry
One load or constraint of a load case.
In the namespace femjob. Declared in src/libs/libfemjob/femjob/LoadCase.hpp.
Detailed description
On a position selector or a node set, `force` is the TOTAL force, spread evenly over the selected nodes, as `fem::FEModel` applies it (construct-fea-solve D2 says why that is not by area). On faces, the job spreads it by face area (§FEJ-3). A `pressure` acts on faces only: `pressure` is one number, positive into the part.
