Define normal enforced velocity (Abaqus)
The Normal type lets you select element or geometry faces to define an enforced velocity normal to the selected surface.
Choose Home tab→Loads and Conditions group→Constraint Type list→Enforced Acceleration .
In the Enforced Velocity Constraint dialog box, from the Type list, select Normal.
In the Model Objects group, click Select Object and select the curve, point, mesh point, polygon face/edge, or element to apply the enforced velocity to.
In the Magnitude group, in the Velocity box, enter the velocity as constant values or expressions. For more information, see Expressions.
Click OK.
