Objective:To perform meshing of the side door model without any off elements and proper mesh flow with less tria concentration

Procedure:

Step 1: The Midsurface was extracted by offset Options in surface edit ,before this model was checked for the geometry

Fig : Midsurface Side door Fig : Surface edit(offset)

Step 2: The Model was having T joint sections on the surface which were further extended using surface edit option and further it was cheked for free edges and Damaged surfaces

While extending the surfaces the surface was getting toggled in few areas due to some issue in the mid while offsetting

Fig : T joints

Step 3: The Midsurface finally was meshed, the rins were meshed first off all and then the flat surfaces assuring the connectivity.

Step 4: After meshing the T joints the rest surface were meshed and Mesh edit was done by remeshing the elements

Fig : fully meshed surfaces

Step 5: The Remeshing was done by Automesh and Remesh tab in 2D , the desired elelments were selcted and remeshed

Step 6: Then finally quality clean up was done for the elemnts failing for the Quality parameters ,this was done by Quality Index tab in 2D and few which were not able to clean by the Tab QI were remeshed and few were cleaned manually

Step 8: Then finally the Elements were checked for Edges through the Tools tab

Conclusion: The Model was meshed with given quality criteria such that it passes all limitation for simulation

Learning Outcomes : The model was a Quite Tideous one , so many problems were faced during midsurfacing and meshing

Then i gained an idea how to cope up with difficulties faces during doing the Project,learned how to take mid ,extract and mesh the Tideous surfaces
