|
// Description : Defines a cylinder inside of which all forces are
|
|
// tangential to the theta of the particle wrt the
|
|
// z-axis in local coord. space. This happens by
|
|
// assigning the force a node by which the cylinder is
|
|
// transformed. Be warned- this will suck anything
|
|
// that it can reach directly into orbit and will NOT
|
|
// let go.
