15.1. Speed
[2D, 3D]: This is the default movement control (See Fig. 15.1.1.and Fig. 15.1.2.), which specifies the speed and direction of a object. The speed may be defined in one way of hte following ways.
-
Constant
-
Function of stroke of the primary object
-
Function of time
-
Function of force (load) on the object
-
Proportional to the speed of another object
-
Sinusoidal function
When an object is rigid, the entire object will move at the assigned speed. When the object is elastic, plastic, or porous, each node with a movement boundary condition assigned will maintain the assigned speed. Note that movement boundary conditions should never be assigned for all surface nodes. In general, no more than 1/2 to 2/3 of the boundary nodes on an object should have movement boundary conditions.
Symmetry planes are defined with V=0 boundary conditions perpendicular to the applied surface. Due to limitations of border extraction during remeshing, parallel symmetry planes should be defined using at least one rigid symmetry surface, instead of V=0 boundary conditions on both sides of the object.
Current Force field is added for all movement types and user can observe the current force at different steps.
