Description
The ROTVEL entry defines values for an initial rotational velocity.
Format
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
| ROTVEL | TID | SID | Ax | Ay | Az | Bx | By | Bz | |
| OMEGA | TYPE | Vx | Vy | Vz |
Example
| ROTVEL | 10 | 8 | 0. | 0. | 0. | 1. | 1. | 1. | |
| 100. | GRID | -50. |
| Field | Definition | Type | Default |
|---|---|---|---|
| TID | Identification number. | Integer > 0 | Required |
| SID | Set identification number. | Integer > 0 | Required |
| Ai | Coordinates of 1st point on axis of rotation. The axis of rotation is defined as the vector from Point A to Point B. | Real | 0.0 |
| Bi | Coordinates of 2nd point on axis of rotation. The axis of rotation is defined as the vector from Point A to Point B. | Real | 0.0 |
| OMEGA | Rotational velocity about the vector from Point A to Point B in radians/sec. | Real | 0.0 |
| TYPE | Type of Set. Choices are
ALLGRID – All grid points in the mesh are given the initial velocity. For this case the SID is ignored. GRID – All grid points in the set defined by SID are given the initial velocity. ELEM – All grid points in the set of elements defined by SID are given the initial velocity. PART – The SID is interpreted as a property ID and all grid points in the elements that use this property ID are given the initial velocity. |
Character | Required |
| Vx | Translational velocity in the X direction. | Real | 0.0 |
| Vy | Translational velocity in the Y direction. | Real | 0.0 |
| Vz | Translational velocity in the Z direction. | Real | 0.0 |
