Week 12:Project-1-Meshing of Door Inner Panel Challenge

#12 Week Project-1 Challenge-Hyper mesh for FEA Plastic and Sheet Applications

Aim: To extract the mid-surface of the given component and assign the thickness for the side door panel.

Element Quality Criteria:

Import the geometry;

1. Click on the import icon on the main menu bar.
2. Select the import geometry and choose the file, click on import.
3. Then the file will be imported and will be shown in the graphical area as below,

Surface Clean-up:

1. Check the surface for geometrical errors.
2. Check surfaces use the quick edit panel for correction of surface.
3. Use defeature to remove the surface fillets with less than 5mm radius to obtain elements without failing for minimum element size.

Mid-Surface:

1. Create mid surface of the geometry using offset.
2. Click on surface edit and go to offset select the surfaces individually and offset it with by making duplicate of the original surface.
3. Offset the duplicate to middle of the surface.
4. Create & Organize all the mid surfaces into the new collector.

Meshing:

1. Ensure the criteria file is applied and the values are properly applied.
2. Click on Auto-mesh from the 2D menu in the menu bar.
3. Set the element size to 4, select the element type as mixed (quads & tria’s) and select the surface to be meshed and click on mesh.
4. Mesh will be created on target surface.
5. Adjust the number of nodes on the either of sides, so that make sure rotational quads are not formed on the surface.

Assign thickness:

1. Separate the mid-surfaces into new collectors based on the thickness of parent geometry.
2. Create different properties and assign different thicknesses as per the parent geometry.
3. Assign the properties to different collectors.
4. By 2D Transitional view we can see the elements with assigned thickness.

The Output:
