Week 12:Project 2-Meshing of Rear Wheel Holder challenge

                                                                                     PROJECT 2 - MESHING OF REAR WHEEL HOLDER

AIM

To mid-surface and mesh the given Rear wheel holder component by using the given quality criteria and assaigning thickness to the areas.

OBJECTIVES

1. Mid-Surfacing the given component using proper tools.
2. Meshing the component by using the given quality criteria.
3. Assaigning thickness to the components.

MODEL

PROCEDURE

Importing the IGES model to the hypermesh from import geometry and manuely looking for some geometrical errors .

move the components from the organize panel from tools in order to make a single component.

features and geometrical errors can be captured by using replace nodes,filler surface , toggle lines/edges....etc

MID-SURFACING

After clearing all the geometrical errors like free edges , manifold lines .....etc . The component is taken for mid-surfacing.

Mid-Surfacing is obtained by Automid options .

The path is ,

    Geometry >> mid-surface >> auto midsurface >> extraction options >>Offset + planes >> auto extraction

    >> select the surface >> extract

As it was a uniform thickness component of sheetmetal mid-surface is extracted very easily using auto mid tools .

Removed the buttons which are shown below because it will be difficult to capture that area as well mesh flow will not be proper.

Except this feature, all the other features should be captured with proper element quality.

MESHING

Mesh the mid-surfaced model by setting the quality prameters and criteria as per the given objectives .

Meshing is carried out by using the path ,

2D >> Automesh >> select the surfaces to be meshed >> mesh type = mixed >> set the element size as per requirement >>mesh

Improve the mesh flow and clear the elements which was failing for quality using rebuild mesh , quality index tools like element optimize , smooth

node optimise , the tria element , combine tria element , swap edge ....etc.

ASAIGNING THICKNESS

Assaign thickness for the component by creating a property card to the component.

CONCLUSION

Mid-Surfaced , Meshed and assaigned thickness for the given Rear wheel holder model using hypermesh .
