Distributed normal force in the direction of
the outward normal at the edge of a geometry.
This distributed term is translated into equivalent nodal force terms
on the edges of elements.
This option is meant for 2D and 3D calculations.
Also the record **force_element_edge_normal_geometry** should
be specified, and optionally the record **force_element_edge_normal_time** can be specified.
