Project 2

AIM:

To extract the midsurface for the given component and mesh it with given quality criteria.

METHODOLOGY:

1. Importing the model.
2. Cleaning the imported geometry.
3. Extracting the midsurface for the geometry.
4. Meshing the surfaces with given quality criteria.

INTRODUCTION:

A spare tire well is used to store the tire which is not in use. Usually a stiff cardboard is used to cover the spare tire.

PROCEDURE:

Importing:

• Click on open, open the folder in which file is located.
• Click on ‘open’.

Figure-1(model import)

Clean up:

• Delete all the solids of the geometry.
• Clean up the each component using different options like

1. Toggle
2. Add / remove point
3. Split surf node
4. Split surf line

• Toggle all unwanted lines in the geometry.

Midsurface & Meshing:

• Go to geom panel, click on ‘midsurface’.
• Select the component, add the offset value and click on ‘extract’.
• After extracting midsurface, split the component into small parts.
• Set the criteria in criteria editor module and click on apply.
• Go to 2D panel and select ‘automesh’.
• Select the surface and set element type as ‘5’ and mesh type as mixed.
• Click on mesh.
• Solve the errors if any by quality index options.
• Select the appropriate option to solve the error.

Assign the thickness:

• Go to mesh options, select the ‘assign’.
• Select ‘midmesh thickness’.
• Set the parameters and click on calculate thickness.
• It automatically creates the thickness properties and assign it.
