Week 5

ABSTRACT:

Checking the geometrical errors and meshing the model with given quality criteria and also using the tetra elements to model with no kinks and dips.

METHODOLOGY:

• Importing the model.
• Cleaning up the geometry.
• Meshing the model with given quality criteria.
• Using the tetra elements to mesh the volume.

INTRODUCTION:

Rear mirror is one of the component comes safety.It is used to see the vehicles coming from backside or rear. The rear mirror can be adjusted according to the driver convience. It plays an important role in safety.

PROCEDURE:

Importing the model.

Figure-1(model importing)

Topology:

1. Checking the geometrical errors.
2. Deleting the unnecessary cons if any.
3. Stiching all remaining cons.

Figure-2(geometry check up)

SURFACE MESHING:

1. Applying the quality criteria to the model.
2. Meshing the model with spotmesh by tria elements like orthotria and tria elements.
3. Checking the quality of the mesh and rectifying the errors if any.

VOLUMETRIC MESHING:

1. Defining the volumes using define option(auto detected).
2. Confriming in the list option.
3. Selecting the model and applying the meshing using tetra rapid option.
4. Select the volumes manually and apply the mesh.

Learning outcome:

Operating the volumetric meshing.

Usage of different options in volumetric mesh like

1. define
2. list
3. tetrarapid
4. tetraFEM
5. Fix quality.

RESULT:

The given model is checked with geometrical errors, cleared the quality criteria and applied the mesh with tetra elements with no off elements.
