Week 12 - Project-1

Objective:

To create mesh for the given component and assign thickness.

Procedure:

The complexity of the entire geometry is reduced by spliting the entire components is split into various components.

Select 2D panel-> surface edit -> trim with planes-> select the surfs-> select the split points. The surface gets splited as shown. 

Measure the thickness of the sheetmetal by pressing F4.

To Extract the middle surface mannually by going to 2d-> surface edit-> offset. 

Certain errors like the missing surface, overlapping and intersecting surfaces can be rectified using the quick edit option also.

Go to edit parameters-> set the quality crietria, as mentioned in the above tabular column.

The surface that needs to be meshed iss selected by selecting automesh -> select the surface-> set the target element length as 4mm-> click on mesh.

The entire component is meshed surface by surface. Inorder to obtain a good quality mesh flow with lesser tria concentration, the meshing procedure is carried out surface by surface this results in proper flow and better capturing of the surface with the meshing elements.

Adjust the quality of the mesh as required, by re-selecting the elements and remeshing it once again. Repeat the process untill a proper mesh is obtained.

The seperative components and elements are assigned into seperate component collectors. As shown.

The quality of the mesh can be further adjusted by going to 2d-> quality index-> use the optiions such as place node, drag tria element, element optimization, node optimization, etc,. thus the above options results in higher quality mesh.

Perform periodical checks using the options tools-> check elements-> enter the values and if errors shows up the particular region of mesh is rectified using the above stated options.

create a new property collector such as shells, covers, ribs and enter the appropriate thickness within the property card.

Now catagorize the elements in each respective collector and assign the property card to the component collectors.

This results in respective element thickness.

Result:

Thus the sidedoor plastic component is mesh captured as per the quality crietria, along with assigning the thickness with better mesh flow.
