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: Density tool
to edit element density and size along surface edges.
The Edit tools work for tessellated
geometry. If the input is b-spline geometry, first convert to discrete geometry
using the Convert tool.
The local edge element size
approximation is based on edge density value and length. Hence, it can vary slightly for
two edges with the same density value.
From the Geometry ribbon, click the Edit > Density tool.
Figure 1.
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.
Left-click to select the edge(s) to modify.
In the microdialog, click the icon to switch the value
being defined to either element density or element size.
Edit element density or size in the following ways:
Increase individual edge values by holding Ctrl while left-clicking on an edge; decrease individual edge values by
holding Ctrl while right-clicking on an
edge.
Scroll edge values by holding Ctrl while
scrolling the mouse wheel up and down. Hovering directly over an edge will
only modify that edge; hovering over empty space will modify all selected
edges.
Specify an edge value in the microdialog and
press Enter. If multiple edges are selected, a
common value will be applied. If multiple edges with different edge values
are selected, use the arrows in the microdialog to
modify individual edge values simultaneously, without applying a common
value.
Tip: Clear your selection by left-clicking in empty space.
