Replace panel |
|
|
|
|
Use the Replace panel to relocate one node to the position of another or manually equivalence two nodes.
|
|
|
In this example, the dark gray node is replaced by the node highlighted by the green circle. The tria above the two selected nodes is destroyed, and the quad below them converts to a tria. |

In this example, the replace node function is used to close a discontinuity in the mesh. The gap shown in the left image is closed by replacing a node of the yellow element with a node of the blue element. The equivalence option will redefine the yellow element to use the same node ID as the blue element so element connectivity is ensured. |

The Replace panel is organized into four columns from left to right. The first column includes node selectors, used to pick the two nodes that will be combined. The second column contains controls to determine the location of the combination, and display the distances between the combined nodes in the X, Y, and Z axes. The right-hand column contains control buttons to reject the replacement or exit the panel.
Replacements occur immediately upon selecting the nodes; there is no command button to trigger the replacement, only to reject (undo) it. The replacement is made permanent when you leave the panel or combine another node pair, so you cannot reject it after leaving the panel and returning.
When a node replacement will destroy an element, a pop-up window warns you of this fact.
| • | Yes replaces the node and destroys the element. |
| • | No aborts the replacement. |
| • | Yes to all automatically accepts the current replacement and all subsequent replacements, suppressing the pop-up prompt until you exit and re-enter the panel. |
| • | No to all automatically aborts the current replacement and any subsequent replacements that would result in a destroyed element, suppressing the pop-up prompt until you exit and re-enter the panel. |
There are no subpanels on the Replace panel. All inputs and command buttons are located on the main panel.
Input |
Action |
replace: node |
This node will be relocated to location of the second node. |
with: node |
This node will be retained. Depending on the settings, it may or may not remain in its original location. |
equivalance |
This option redefines any entities referencing the first node, to replace that reference with the node ID of the second node.
Without the equivalence option activated, the replace operation simply relocates the replaced node to the location of the retained node; both nodes will remain as distinct, coincident entities. In the example above, this would cause the tria element to become a sliver. |
at mid-point |
This option combines the two nodes at the midpoint between their original locations. Affected elements may be destroyed or changed.
|
total = |
The total distance between the original replace node and with node. This is a read-only field (you cannot change the values) that populates when the replacement occurs. |
x dist = |
The global X component between the original replace node and with node. This is a read-only field (you cannot change the values) that populates when the replacement occurs. |
y dist = |
The global Y component between the original replace node and with node. This is a read-only field (you cannot change the values) that populates when the replacement occurs. |
z dist = |
The global Z component between the original replace node and with node. This is a read-only field (you cannot change the values) that populates when the replacement occurs. |
The following action buttons appear:
Button |
Action |
replace |
Perform the node replacement. |
return |
Exit the panel. |
