Week- 5 - Solid meshing
CHALLENGE REPORT :-
Aim:
For the given Rear view mirror component, check for the geometrical errors and mesh the Surfaces with the given 2D element Quality criterias given below.

Use tetra elements to mesh the Volumes defined in the model and check for the below quality after Volume meshing.

Procedure:
i - At first get the model and starts to check the geometry of the given model.
ii - If the given model has any geometry errors, then at first clear the geometry of the given model.
iii - After clearing the geometry errors, go to mesh parameters and change to tria mesh.
iv - By using the spot mesh command select all the complete model .
v - After selecting all the entityies, select the faces of the givem model.
vi - After meshing, go to volume mesh and define the module.
vii - Next clear and make it smooth for meshing.
viii - Give the quality criteria values as per given.
ix - Now use tetra rapid to clear all unstructured mesh.
x - After meshing the entire surface if there are any quality criteria issues try to 'reconstruct' it or try to 'improve' the mesh flow.
xi - All the 3D elements in your model should clear the above-mentioned quality criteria and the features in the model have to be captured properly with good mesh flow
xii - Do the same procedure for all the parts.
LEARNING OUTCOMES:
a) By working on this Rear view mirror , I learned many tools to handle.
b) I learned to use boolean operations, property id & material id.
c) I LEARNED about the 3D mesh flow..
d) I learned to insert and delete hopt point & many ANSA tools.
e) I learned about the quality criterias.
f) I learned many methods of meshing the model.
CONCLUSION:
The given Rear view mirror is studied, analysed, Geometry checked, thickness has measured, Mid surfaced, & meshed properly.
