Engine Keyword With ALE links on grid velocities, given nodes
are linked to the given main grid velocities. You can specify the direction or a combination
of directions. This definition is only taken into account during the current
run.

Keyword3
A combination of X, Y, and
Z:X, Y, Z, XY, XZ, and XYZ
Keyword5
GRNOD or
NODES defines the way to provide secondary
nodes.
node_ID 1
First main node
number.
node_ID 2
Second main node
number.
ID i
Secondary node or node
group identifiers (depending on Keyword5 )
Comments
This card replaces /VEL/ALE (Obsolete) Engine card
from previous versions.
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 ).
Radioss will superimpose the grid velocities if different ALE links are defined in both
Starter and Engine for the same node.
