The Prescribed Velocity node adds an edge (3D), boundary (2D), or point (2D and 3D) that prescribes the translational or rotational velocity in one or more directions. The prescribed velocity condition is applicable for Time Dependent and Frequency Domain studies. With this condition it is possible to prescribe a velocity in one direction, leaving the beam free in the other directions.
Select one or all of the Prescribed in x direction,
Prescribed in y direction, and for 3D models,
Prescribed in z direction check boxes. Then enter a value or expression for
vx,
vy, and for 3D models,
vz.
