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
- 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 - Step offset mode
- This option allows finer control of how stepped geometry (one side continuous surface, and opposite side steps) is captured. This option is valid only when flatten connections is enabled. Values can be:
- 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 6. Option Off
Figure 7. 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 Off
Figure 9. Option On - Defeature ribs width factor
- The minimum size factor for removing small ribs. Ribs closer than this factor times minimum size will be suppressed. Default is 0.9.
- Defeature openings with width <
- The maximum width for removal of small holes and openings.

Edit Edge Subpanel
- create mid-edge
- Create a new mid-edge, optionally using the input geometry as a
guide:

Figure 14. With Guides
- split by two nodes
- Create a new edge between two nodes.
Figure 15. Before
Figure 16. After - split by node-edge
- Create a new edge between a node and an edge, using a shortest,
tangential or mixed path.

Edit Face Subpanel
- 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 30. After - repair face
- Attempt to fix topological problems (holes/gaps/cracks, intersections,
slivers, overlaps) in the mesh and remesh the face.
Figure 31. Before
Figure 32. After - detect intersections
- Detect intersecting element clusters and holes/gaps/cracks, and create
element sets for further handling.
