This dialog handles reference nodes which may be helpful in:

• driving the topology optimization process and
• more detailed monitoring of displacements of particular FE nodes.

Any number of reference nodes can be defined as needed.

To define a new reference node ...

1. Hold down the Alt key and use the left mouse button (Alt key + LMB) to click the node to be defined as a reference node. The newly defined reference node is marked by a green cube marker.

2. Optionally enter any note to describe the node.
