Procedure

1. Open the given CAD and understand the geometry for midsurface generation.
2. Since its single surface model with uniform thickness, automidsurface can be used.
3. For easy and quick meshing process the surfaces are again spilt into small parts.
4. Quality criteria are checked and fails are removed.
5. Equivalence is performed to maintain connectivity between the elements.
6. Property and thickness are assigned to the component.

Briefing about the options used to generate the 2d mesh.

In the Geometry panel

• Defeature was used to remove the surface fillets and pin holes in this case, holes with less than 5mm were removed.
• Quick edit was to toggle , replace and filler surface for geometry clean-up
• Midsurface, here Auto midsurface was used to generate the midsurface from the closed geometry.

In the 2d panel

• Automesh was used to generate the mesh according to required size.
• Smooth and quality index used for editing and cleaning the mesh for quality criteria

Tool panel

• Check elems was used to find out failed elements
• Edges were used to equivalence and remove unwanted edges from mesh

Results

FE Model is generated.
