Node and Nodeset Repositioning

A capability to reposition nodesets and individual nodes is provided. This capability will retain all the current connectivity of the nodes involved, but it cannot guarantee that the new locations of the moved nodes do not form intersections with previously existing mesh or geometry. This capability is provided to allow the user maximum control over the mesh model being constructed, and by giving this control the user can possible create mesh that is self-intersecting. The user should be careful that the nodes being relocated will not form such intersections.

The user can reposition nodes appearing in the same nodeset using the NodeSet Move command. Moves can be specified using either a relative displacement or an absolute position. The command to reposition nodes in a nodeset is:

Nodeset <nodeset_list> Move <delta_x> <delta_y> <delta_z>

The first form of the command specifies a relative movement of the nodes by the specified distances and the second form of the command specifies absolute movement to the specified position. The third form of the command specifies a displacement with respect to a specified surface normal.

Individual nodes can be repositioned using the Node Move command. Moves are specified as relative displacements.

To move a node

  1. On the Command Panel, click on Mesh and then Node.
  2. Click on the Move Node action button.
  3. Select Move XYZ from the drop-down menu.
  4. Enter the appropriate value for Node ID(s). This can also be done using the Pick Widget function.
  5. Enter the appropriate values for Delta X, Delta Y and Delta Z or manually move the node by dragging it to the desired location.
  6. Click Apply.

Note: The constrain to geometry option can be turned off to move the node outside of the geometry.

Node <range> Move <delta_x> <delta_y> <delta_z>

Node <range> Move {[X <val>] [Y <val>] [Z <val>]}

To move normal to surface

  1. On the Command Panel, click on Mesh and then Node.
  2. Click on the Move Node action button.
  3. Select Normal to Surface from the drop-down menu.
  4. Enter the appropriate value for Node ID(s) and Surface ID. This can also be done using the Pick Widget function.
  5. Enter the appropriate values for Distance.
  6. Click Apply.

Node <range> Move Normal to Surface <id> distance <val>

Nodes can also be repositioned using a location or direction specification. See Location, Direction, and Axis Specification for details on the location and direction specification. The command syntax is:

Node <range> Move Location <options>

Node <range> Move Direction <options>
