You can apply point displacement methods on nodes in order to define the boundary conditions of a line in a domain on which the elastic remeshing method has been applied. You can also apply them to define the displacement of control points for lines on which the line deformation method is applied. You have the following options for moving points:
free point
No motion is prescribed for a node designated as a free point. The motion of the node is governed by the method applied on the domain of higher dimension that includes the free point.
direction imposed
When only a direction is imposed on a node, the motion has an amplitude value determined by Equation 35–10 and direction component determined by Equation 35–13.
direction and amplitude imposed
When a direction and amplitude is imposed on a node, the motion has an amplitude value determined by Equation 35–12 and direction component determined by Equation 35–13.
amplitude imposed
When only an amplitude is imposed on a node, the motion has an amplitude value determined by Equation 35–12 and direction component determined by Equation 35–11.
fixed point
When a node is designated as a fixed point, the motion of the node is governed by Equation 35–1. As a result, the node remains fixed at its original coordinates.
