rblock free command

Syntax

rblock free keyword ... <range>

Primary keywords:

spin    spin-x    spin-y    spin-z    velocity    velocity-x    velocity-y    velocity-z

Free the specified rigid block velocities. As a result, rigid block motion reflects the forces acting upon them.

spin

The angular velocity is freed.

spin-x (3D ONLY)

Free the \(x\)-component of the angular velocity.

spin-y (3D ONLY)

Free the \(y\)-component of the angular velocity.

spin-z (3D ONLY)

Free the \(z\)-component of the angular velocity.

velocity

The translational velocity is freed.

velocity-x

Free the \(x\)-component of the translational velocity.

velocity-y

Free the \(y\)-component of the translational velocity.

velocity-z (3D ONLY)

Free the \(z\)-component of the translational velocity.

Usage Examples

Free (remove fixity from all degrees of freedom) rigid blocks in the group supportBlock.

rblock free velocity spin range group 'supportBlock'
