The Deformable Surfaces panel allows you to create a surface that can change shape
during the simulation. It can be used to model a
PointToDeformableSurfaceJoint MDL entity or a
PointToDeformableSurfaceContact MDL entity. The points that are used
to describe the surface can belong to one or more bodies (rigid or flexible).
-
If the Deformable Surfaces panel is not currently displayed, select the desired
deformable surface by clicking on it in the Project Browser or in the modeling window.
The Deformable Surfaces panel is automatically displayed.
-
Specify the type of locations to be used to describe the deformable surface by
choosing Marker or Body/Point from
the Data type drop-down menu.
-
Add, insert, and delete rows and columns.
-
Click the Marker, Body, or
Point collectors and make your selections in the
modeling window, or double-click the collectors and
make your selections in the Model Tree
-
Select an end type from the drop-down menu.
MotionSolve applies a cubic spline interpolation
to represent the surface. The spline interpolation requires assumptions on the
second derivative at the ends. The end type selected specifies the method of
assumption for the second derivative.
