# clump fix command

Syntax

clump fix keyword ... <range>

Primary keywords:

Fix the specified clump velocities. As a result, clump motion is constant in the specified directions.

spin

The angular velocity is fixed.

spin-x (3D ONLY)

Fix the $$x$$-component of the angular velocity.

spin-y (3D ONLY)

Fix the $$y$$-component of the angular velocity.

spin-z (3D ONLY)

Fix the $$z$$-component of the angular velocity.

velocity

The translational velocity is fixed.

velocity-x

Fix the $$x$$-component of the translational velocity.

velocity-y

Fix the $$y$$-component of the translational velocity.

velocity-z (3D ONLY)

Fix the $$z$$-component of the translational velocity.

Usage Examples

Fix the $$x$$- and $$y$$- components of the velocity, and the rotational velocity, of all clumps except those with ID 1, 2, 3, and 4.

clump fix velocity-x velocity-y spin range id 1 4 not


Fix the $$x$$-component of velocity of clump with ID 1.
