structure node free command
Syntax
- structure node free keyword <range>
Primary keywords:
rotation rotation-x rotation-y rotation-z system-local velocity velocity-x velocity-y velocity-z
Free the velocity-fixity conditions for all nodes in the range, thereby allowing these values to change based on the equation of motion. The velocity-fixity conditions are fixed with the
structure node fixcommand.- rotation
rotational velocity in all three rotational degrees-of-freedom (node-local system)
- rotation-x (3D ONLY)
rotational velocity about \(x\)-axis (node-local system)
- rotation-y (3D ONLY)
rotational velocity about \(y\)-axis (node-local system)
- rotation-z (3D ONLY)
rotational velocity about \(z\)-axis (node-local system)
- system-local
allows automatic updating of the node-local system based on the elements that use the node (as described here). This is the default behavior (see
structure node fix system-local).
- velocity
translational velocity in all three translational degrees-of-freedom (node-local system)
- velocity-x
translational velocity in \(x\)-direction (node-local system)
- velocity-y (3D ONLY)
translational velocity in \(y\)-direction (node-local system)
- velocity-z (3D ONLY)
translational velocity in \(z\)-direction (node-local system)
