Description
The INITVEL entry defines values for the initial translational velocity.

| Field | Definition | Type | Default |
|---|---|---|---|
| TID | Identification number. | Integer > 0 | Required |
| SID | Set identification number. | Integer > 0 | Required |
| Vx | Component of initial velocity in the global x-direction. | Real | 0.0 |
| Vy | Component of initial velocity in the global y-direction. | Real | 0.0 |
| Vz | Component of initial velocity in the global z-direction. | 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 |
Remarks
- Initial condition sets must be selected with the Case Control command IC = TID.
- If no TIC set id is selected in the Case Control Section, all initial conditions are assumed zero.
- Initial conditions for coordinates not specified on TIC entries will be assumed zero.
- If the SID references a grid point that is the reference node for a rigid body defined with an RBE2 entry and the PART specification is used for TYPE, the initial condition is applied to the reference node for the rigid body.
- If the SID references the material identification number on a MATR1 entry (the MATR1 entry defines a rigid material) and the PART specification is used for TYPE, the initial condition is applied to the center of mass of the rigid material defined by the MATR1 entry.
