Mesh Checkpoint

The mesh properties are defined in this checkpoint. The following properties are available:

To generate the mesh, right-click on the Mesh checkpoint in the project tree and select Generate Mesh from the context menu or click on the  button in mesh tab. If the geometry has passed the validation, the mesh will be generated. The mesh generation process may take some time depending on the complexity of the geometry and the selected algorithm.

Algorithm

The algorithm used for the mesh generation. The available algorithms are:

1. MeshAdapt
2. Automatic
3. Initial mesh only
4. Delaunay
5. Frontal-Delaunay
6. BAMG
7. Frontal-Delaunay for Quads
8. Packing of Parallelograms
9. Quasi-structured Quad

Max Element Size

The maximum size of the elements in the mesh.

Recombine / Recombination Algorithm

The recombine checkbox. If checked, the mesh will be recombined to form quadrilateral elements.

The available recombination algorithms are:

1. simple
2. blossom
3. simple full-quad
4. blossom full-quad

Full Mesh

The full mesh checkbox. If checked, the mesh will be generated for the entire geometry.

Segmentation

The segmentation checkbox. If checked, segmentation lines will be generated for the mesh.

Silent

The silent checkbox. If checked, the mesh generation will be silent and no messages will be displayed in the log panel.

Airgap

• Tangential Divisions: The number of mesh divisions in the tangential direction of the airgap line.
• Radial Divisions: The number of mesh divisions in the radial direction of the airgap area.

Stator

The mesh size in the stator region is a function of distance from the airgap line. The mesh size from the airgap line to DistMin is SizeMin, and the mesh size from DistMax to the stator outer radius is SizeMax. The mesh size between DistMin and DistMax is linearly interpolated.

The mesh size in the stator region is defined as follows:

• DistMin: The distance up to which the mesh size is SizeMin.
• DistMax: The distance after which the mesh size is SizeMax.
• SizeMin: The mesh size when the distance from the airgap line is less than DistMin.
• SizeMax: The mesh size when the distance from the airgap line is greater than DistMax.
• Windings: The mesh size in the windings region.

Rotor

Similar to the stator region, that is defined as follows:

• DistMin: The distance up to which the mesh size is SizeMin.
• DistMax: The distance after which the mesh size is SizeMax.
• SizeMin: The mesh size when the distance from the airgap line is less than DistMin.
• SizeMax: The mesh size when the distance from the airgap line is greater than DistMax.
• Holes: The mesh size in the holes region. (only for IPMSM and SynRM machines)
• Magnets: The mesh size in the magnets region. (only for IPMSM and SPMSM machines)

Report Mesh Summary

This button prints the mesh summary in the log panel.

v0.7.0: GEO and external mesh sources

The Mesh checkpoint can use the normal Base model, an EMSOptimizer-updated Imported GEO, or an external Imported Mesh.

Source Mode	Content	Mesh generation
Base	Generate from the current eMotorSolution model	Allowed
Imported GEO	Prefer the registered GEO and fall back to Base GEO for missing components	Allowed
Imported Mesh	Use external stator and rotor meshes	Not allowed

Imported GEO and Imported Mesh are mutually exclusive. Verify that the profile is ready and that the GEO/Mesh Status and file names are valid. External meshes must use Gmsh 4.1 ASCII format with the required physical groups. Include ImportedGeometry/ImportedMesh copies when distributing a project.
