Week 12 - Project-1

OBJECTIVE:  

To create 2D mesh model of Side door Panel under specified Element quality criteria.

INPUT:

CAD MODEL IMAGE:

PROCEDURE:

• Import the side door model in HM.
• Creating the Criteria file with the mentioned element criteria.

• As the part is large geometry cleanup was done by splitting the part into four.

• After splitting the surfaces, the mid surface was extracted using offset command. Manual mid-surfacing was preferred as the part was having varying thickness at sections.

• After Extracting the mid-surfaces for each section. Geometry cleanup was performed manually.
• The surfaces were cleaned and optimized for T Connections. For satisfying Element min. sizes and to collect Feature lines Perfectly.

• The surfaces were extended for Ribs and T Connections were made. By using quick edit tool and surface edit it was achieved.

• After this Each surface was meshed by element size 4 mm. While performing meshing on the surfaces the visualization mode was changed to element quality check. It made simple for correction of failed elements and to increase accuracy in mesh generation.

• While correcting mesh it was taken care for capturing feature lines properly to improve post processing accuracy.
• The holes and fillets were achieved properly.

• Simultaneously, The Free edges and open nodes were checked and corrected properly.

• While performing this task I mainly focused on capturing the features properly in mesh. Tried to eliminate maximum Tria element without compromising with the Feature lines.
• After achieving the complete mesh on surfaces, it was checked for open edges. All the open edges were cleared and the mesh was checked for normal.
• After gaining the proper mesh with the mentioned quality criteria “0” Elements were failed.

• After this Property card was made individually for each changed section.

• Component file were made as per thickness and elements were shifted to as per their thickness measured in 3D Model File.

FINAL MODEL IMAGE:

CONCLUSION:

Hence, by this project-1, we understood about complete basic FE modelling over complex part with Connected T Surfaces and maintained proper Element Quality and MidSurfaces ad assigned proper Thickness.
