1. From the Utility page, start the BC’s manager.
2. Give a name, set Select type as imposed velocity and set GRNOD to Nodes.
3. Select the nodes where you want this boundary condition.
4. Set the direction and scale (see the tutorial where direction is set as X and Y scale as -1.0.)
5. Click the Create/Select curve ID > An XY curve editor appears.
6. Create a new curve,
7. Close the XY curve editor, the created curve is assigned to this constraint.
8. Click create to create the velocity boundary condition.

Hello sir,

What do the X and Y represent in curve editor? I guess X is time. I am not sure about the Y axis. Please help.

Thanks in advance.
