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.

This is hidden. Added to include remaining vector component access functions for inline help.

f = wall.vertrex.vel.y(v)

f = wall.vertrex.vel.z(v) (3D ONLY)
