force_element_edge_time index time load time load ...

This record specifies a diagram which contains the factors with which the force_element_edge record with the same index is applied. Linear interpolation is used to extend the time load values to the intervals between these pairs.

If this record is not specified, and the force_element_edge_sine record is not specified, the force is applied at all times with a factor 1.

If no external forces like force_element_edge_time are specified, the internal element forces become zero at free edges to satisfy equilibrium. This causes, by example, temperature gradients to become zero at free edges in heat problems.
