Definition
| Field | Contents | SI Unit Example |
|---|---|---|
| impvel_ID | Imposed velocity block
identifier. (Integer, maximum 10 digits) |
|
| unit_ID | Unit Identifier. (Integer, maximum 10 digits) |
|
| impvel_title | Imposed velocity block
title. (Character, maximum 100 characters) |
|
| fct_IDT | Time function
identifier. (Integer) |
|
| Dir | Direction: X, Y, and Z in
translation; XX, YY, and ZZ in rotation. (Text) |
|
| Skew_ID | Skew
identifier. (Integer) |
|
| grnd_ID | Identifier of the node
group on which the imposed velocity is applied. Input is obligatory.
The imposed velocities will be applied only on nodes that belong to
a node group. (Integer) |
|
| Ascalex | Abscissa scale factor for
fct_IDT. Default = 1.0 (Real) |
|
| Fscaley | Ordinate scale factor for
fct_IDT. Default = 1.0 (Real) |

Comments
- The velocity direction must be right justified in the ten characters of field number 2.
- The translational velocity is not available, if it is applied on a node with a null mass.
- The rotational velocity is not available, if it is applied on a node with a null inertia.
