/ALE/LINK/VEL - Defines Links on Grid Velocities
With ALE links on grid velocities, given nodes are linked to the given master grid velocities. You can specify the direction or a combination of directions. This definition is only taken into account during the current run.

Data |
Description |
Iform |
Formulation flag (Integer) = 0 (linear):
= 1 (maximum): WN1 = WM1 if WN1 = WM2 if = -1 (minimum): WN1 = WM1 if WN1 = WM2 if |
Keyword3 |
A combination of X, Y, and Z: X, Y, Z, XY, XZ, and XYZ |
Keyword5 |
"GRNOD" or "NODES" defines the way to provide slave nodes |
M1 |
First master node number. |
M2 |
Second master node number. |
IDi |
Slave Node or node group identifiers (depending on Keyword5) |
| 1. | This card replaces /VEL/ALE Engine card from previous versions. |
| 2. | Using formulation Iform=0 requires an ordered node list. Using Iform=0 with Keyword5=GRNOD also requires an unsortable node group (refer to /GRNOD/NODENS). |
| 3. | RADIOSS will superimpose the grid velocities if different ALE links are defined in both Starter and Engine for the same node. |
