In CFD modeling, input parts can have topology issues, like free surfaces and self-intersections, and part assembly
issues, such as parts with very close proximity and intersecting parts. Manually connecting these parts can be time
consuming and require expertise in certain tools. The Wrap tool can generate a watertight manifold model from dirty input with considerably less manual work.
Use the Edit: Replace tool
to relocate and replace the positions of nodes.
The Edit tools work for tessellated
geometry. If the input is b-spline geometry, first convert to discrete geometry
using the Convert tool.
From the Geometry ribbon, click the Edit > Replace tool.
Elements are colored according to how
well they adhere to the pre-set quality requirements defined in the criteria
file.
Select an element issue type from the guide bar.
Quality
Checks for quality as defined in quality criteria.
Intersections
Checks for intersecting elements.
Face angles
Checks for folded or sharp angle elements.
Optional: Find all elements at or below a certain quality level.
Click Find on the guide bar.
Increase or decrease the number of layers around patches of failed
elements by clicking or on the guide bar.
Review the next or previous patch of failed elements by clicking
or on the guide bar.
Select a replacement method from the guide bar then
select nodes/element edges. A preview of the collapsed edge is shown when you
hover the mouse over the entity (FE Edges).
Method
Node Replacement Steps
One to One
Select a node to relocate and replace.
Select a target node.
The second node replaces the
first.
Note: You can also perform one to one replacement by selecting an
element edge to collapse. Selecting an element edge automatically
performs midpoint replacement.
Multi to One
Select multiple nodes.
From the selected nodes, left-click on a single target
node.
All other nodes are relocated to and replaced by
this node.
Multi to Multi (Node Pair)
Select a node to relocate and replace.
Select a target node.
Repeat this process as many times as desired.
Left-click on a target node or click
Replace on the guide bar to replace all nodes at once.
Multi to Multi (Node Path)
Select nodes by path to relocate and replace.
Select target nodes by path.
Repeat this process as many times as desired.
Left-click on a target node or click
Replace on the guide bar to replace all nodes at once.

Use the Edit: Replace tool to relocate and replace the positions of nodes.
Access
Go to Geometry > Edit > Replace.
Options
Replace at midpoint
Combine nodes at the midpoint of their original locations.
Affected
elements may be destroyed or changed.
Smooth
Smooth the mesh with the following number of layers.
Number of layers
Change the number of adjacent element layers to smooth.
