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 Enclosure tool can generate a watertight manifold model from dirty input with considerably less manual work.
Use the Derived Region tool to create enclosed and offset regions around a selection – which can be used to define
volumetric refinement levels – or create projected regions in a given direction.
Once the baseline model is prepared, you can define morph volumes, morph geometry, create design shapes and run DOE
studies. These tool work for both AcuSolve and ultraFluidX-based workflows.
Use the Repair tool to find, review, and fix issues in the mesh.
Before you begin, add surface mesh to the model.
Note: This tool only works on visible surfaces. For better
visibility, first isolate surfaces with mesh issues then use this tool. To do that,
go to the Mesh ribbon, set the entity selector to
Surfaces, then right-click and go to Find and Isolate > Mesh Checks and select the required mesh check option.
From the Mesh ribbon, click the
Repair tool.
Figure 1.
Note: This tool is also available on the Discrete ribbon
for working with FE or mixed geometry.
Optional: Click on the guide bar to update
check thresholds.
Optional: Click Find to update the checks.
Since updates are done automatically, clicking Find is
required only if checks are not in sync or visibility has been updated.
Select a check to work on from the first drop-down menu on the guide bar.
Select an option to fix the issues from second drop-down menu.
This list will change based on the selected check.
Navigate through and review each error.
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.
Define any additional options then fix the errors in the following ways:
Hover over a red highlighted error patch and left-click to fix that
particular issue using the options defined on the guide bar.
Click Fix All on the guide bar to fix all errors at once.
Note: If any error checks can not be fixed using the
options provided in the Surface repair tool, isolate surfaces and visibly
review mesh issues.
