Force_Balance
Discussion
This Property
adds a term proportional to the time derivative of
the Displacement to the Force_Balance equation. Specifically, it adds
a contribution
to the term in Eq. (6.120). is a scalar given by the
parameter damping
.

This property is unphysical because it breaks Galilean invariance. It was added for debugging purposes. It may, however, be useful to add stability to the numerical solution in some cases. |
