Week 6-Meshing of Hood Challenge

Title: PREPROCESSING OF HOOD USING HYPERMESH

Aim: To create mesh on Hood using Hyper mesh and extract mid-surface.

Provided model

Steps required:

• Geometry import and cleaning.
• Mid-surface extraction and property assignment.
• Surface blending within the specified quality standards.

Procedure:

Step 1:Geometry import and cleanup:

• Go to file >> Import >> choose the file >> Import to import the geometry.
• The geometry is examined for any missing surfaces or triple cons after being imported.
• The geometry is prepared for the mid-surface extraction if there are no defects in it.

Step 2:Mid-surface extraction and property assignment

• Any of the four approaches listed below can be used to extract mid-surface.

1. Offset + plane + sweep.
2. Offset + plane.
3. Offset
4. Skin Offset.

• Go to geom >> mid-surface >> choose any extraction option >> choose the surface >> extract to extract the mid-surface.
• This task makes use of offset, plane, and sweep.

Step 3: Producing mesh that meets the specified quality criterion

• For optimal mesh flow, the geometry is divided into smaller rectangles before mesh generation.
• Go to 2D >> automesh >> choose the surface >> mesh to create a mesh. The elements are chosen, then the mesh is modified to ensure correct flow.
• The cleaning tools option, which is included in the quality index, can be utilised if any items are failing for quality.

Conclusion:

Mid-surface is retrieved from the provided hood panel, and mesh is created in accordance with the provided quality standards.
