Week 5

REAR-VIEW MODEL

AIM:

To remove geometry errors and perform volume mesh using tetra element with the given quality criteria

PROCEDURE:

1.Open the rear view mirror model

2.Do the topo operation on the whole geometry to join nearby edges. change the element length to 1mm to visualize the geometry properly

3.Run a geometry checks on the whole geometry by using tools from menu. this shows the geometry errors that need to be cleared.

4. after clearing errorsd confirm by running geometry check again

5.the given component is solid so we will be doing volume meshing for this model capture curved surfaces properly,where as normal trias will be used for capturing flat surfaces

6.Before meshing we will assign the reqiured mesh parameter and the quality criteria .

7.mesh the component surface area of the model with tria element such that quality criteria fulfilled define the model volume so that volume mesh can be generated for the current model. 3 seperate volume were defined by using the define volume mesh option.

8.after defining volume, go to the list option under volume in volume mesh module. the list option will show the list of define volumes.we can now perform tetra mesh on the defined volumes by right clicking on each volume and choosing either tetra rapid or tetra FEM method.

9.checks for the quality of the element in the hidden mode if there are quality errors,they need to be fixed .

10.finally,tool kinks or dips on the surface we must ensure that there is no kinks or dips on the surface

RESULT:

a.performed geometry cleanup

b.performed tetra meshing will all element passing the quality criteria.
