Midmesh Panel
Use the Midmesh Panel to automatically generate a mesh at the midplane location, directly from the input geometry (components, elements, solids or surfaces), without first creating a midsurface.
Create Subpanel
Use the Create subpanel to control the resulting midmesh output.
- entity selector
- Select the source used to create the midmesh.
- Destination component
- Select which component newly created midmeshes are placed in.
- Ignore flat edges
- Do not imprint flat edges from the input geometry onto the
midmesh.
Figure 1. Option Off
Figure 2. Option On - Flatten connections
- Aligns/flattens the midmesh at ribs/connections.
Figure 3. Option Off
Figure 4. Option On - Edit criteria
- Set the minimum size and target element size settings in the criteria file to control the resulting midmesh via the Criteria File Editor.
- Extraction size
- The midmesh extraction size. By default, this is taken as the target element size from the criteria file. This can be set smaller than the target size, though that is not recommended unless there are problems extracting at the target size.
- Minimum size
- Minimum element size allowed in the finalized mesh. This in combination
with the ‘suppress proximity edges factor’ and 'combine non-manifold
edges factor’ can ensure that the output mesh is ready for rebuild with
the same criteria.
Can only be modified in the Criteria File Editor.
- Suppress proximity edges factor
- The minimum size factor for removing edges within proximity. Edges
closer than this factor times minimum size will be
suppressed.
Figure 5. Option Off
Figure 6. Option On - Combine non-manifold edges factor
- The minimum size factor for joining non-manifold edges. Non-manifold
edges closer than this factor times minimum size will be
combined.

Figure 8. Option On - Defeature openings with width <
- The maximum width for removal of small holes and openings.

Edit Edge Subpanel
Use the Edit Edge subpanel to repair 1D topology edges.
- create mid-edge
- Create a new mid-edge, optionally using the input geometry as a
guide:
Figure 11. Before
Figure 12. Without Guides
Figure 13. With Guides - split by two nodes
- Create a new edge between two nodes.
Figure 14. Before
Figure 15. After - split by node-edge
- Create a new edge between a node and an edge, using a shortest,
tangential or mixed path.

Figure 18. Tangential Path
Figure 19. Mixed Path - delete edge
- Delete an edge.

Figure 21. After - t-edge align
- Align/flatten a t-connection edge to a surface.

mesh:

Edit Face Subpanel
Use the Edit Face subpanel to correct issues with midmesh faces.
- fill face
- Create a mesh within a closed 1D topology loop, attempting to keep
tangency. Optionally, the 1D loop can be deleted, keeping only free and
non-manifold edges.
Figure 28. Before
Figure 29. After - repair face
- Attempt to fix topological problems (holes/gaps/cracks, intersections,
slivers, overlaps) in the mesh and remesh the face.
Figure 30. Before
Figure 31. After - detect intersections
- Detect intersecting element clusters and holes/gaps/cracks, and create
element sets for further handling.
Figure 32. Before
Figure 33. After - align face
- Align a selection of elements to an input geometry surface:
Figure 34. Before
Figure 35. After - An optional offset can be specified to align the mesh at a given
distance away from the surface:
Figure 36. Offset - Optional locking of boundary nodes of the selection will treat them as
anchors:
