block.vel
Syntax
- v := block.vel(blp)
Get the velocity vector of a block. If the block is rigid and joined to other blocks, the angular velocity of the entire joined volume is returned. If the block is deformable, this returns the average value of the gridpoint velocities.
Component Access
f := block.vel
(blp)->x
- f := block.vel.x(blp)
Get the \(x\)-component of the velocity vector of a rigid block.
Access other vector components (\(y\), \(z\)) 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 (block.vel(blp,<int>)
) 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.
