Project-2-Meshing of Door Inner Panel Challenge

PROJECT-2: MESHING OF DOOR INNER PANEL

AIM:

For the given model, extract the mid-surface and generate its mesh maintaining the required quality criteria.

CAD MODEL:

PROCEDURE:

• Open the model and view in By Topo mode. Check the surfaces for geometric errors or edge connectivity.

• Use Quick Edit panel to toggle the edges (release the attached edges).

• Replace points to eliminate stray points and toggle the edges.

• View the geometry using Wireframe mode to check edges and Toggle them if required.
• Suppress unwanted connections on the surface.

• Create a new surface using the reference line and the neighbouring mid-surfaces.

• Select the Offset+Planes option from Extraction options to create the mid-surface.

• Delete deformed surfaces from the mid-surface.
• Create new surface using Spline panel in 2D menu.

• Use trim option to cut the surfaces and delete the unwanted portion of the trimmed surfaces.

• Features with thickness more than 6 units are represented as shown below.
• Use node panel and line panel to construct the outline of the feature and extend it to the base.

• Remove fillets of the ribs to extract mid-surface by Defeature panel in Geom. menu.

• Offset/Translate the side to the mid point.

• Toggle unnecessary construction lines or the feature lines that might affect the quality criteria of the mesh.

• Input the required values in the Criteria file settings.

• Set the mesh parameters in the Mesh settings.
• Mesh the entire surfaces maintaining the quality criteria and mesh flow.
• Mesh-edit panel can be used to stitch perpendicular surface mesh by Imprint/Extend option.

• Check and clear free edges from the model.

Final Model:

RESULT:

• The given door inner pannel model has been meshed by generating mid-surface. Some of the elements have been failed for quality criteria due to minimum length.
• Elements are assigned with different thickness values in the property card.
