wall.vertex.vel
Syntax
- v = wall.vertex.vel(v)
- wall.vertex.vel(v) = v
Get/set the vertex velocity.
Note
If the vertex velocity is set to a non-zero value, then the wall translational/angular velocities are set to 0. The user is responsible for ensuring that the wall remains manifold in these circumstances.
Returns: v - vertex velocity vector Accepts: v - vertex velocity vector Arguments: v - vertex pointer
Component Access
f = wall.vertex.vel (v)->x
wall.vertex.vel (v)->x = f
- f = wall.vel.x(v)
- wall.vel.x(v) = f
Get/set the \(x\)-component of the vertex velocity.
Note
If the vertex velocity is set to a non-zero value, then the wall translational/angular velocities are set to 0. The user is responsible for ensuring that the wall remains manifold in these circumstances.
Returns: f - \(x\)-component of the vertex velocity vector Accepts: f - \(x\)-component of the vertex velocity vector Arguments: v - vertex pointer
Access other vector components (\(y\), \(z\) (3D ONLY)) by substituting the component name where \(x\) appears above. See Member Access Operator for information about accessing members from data types using ->.
Deprecated Component Access
Component access by adding an optional integer in the function arguments (e.g., f = wall.vertex.vel(v, 3)) is deprecated. It remains available but will not be supported in future versions. See Component Access with Integers in FISH on the Deprecated Commands and FISH page for details.
