pnt

- FemElement3d to attach the point toloc
- point location with respect to the element. If null
,
will be assumed to be pnt.getPosition().reduceTol
- try to reduce the number of attached nodes by
removing those whose coordinate values are less then this number.
A value of zero ensures no reduction. If reduction is desired,
a value around 1e-5 is reasonable.public void addMassToMasters()

, then any component referenced
by this component should itself be set to a copy. This
should be done first checking copyMap
for an
existing copy of the referenced component. If there is no existing
copy, then a copy should be created by calling copy
recursively and adding the new copy to copyMap
