Week - 4 - 2D meshing for Plastic components

MANUAL MID-SURFACE CREATION AND 2D MESH GENERATION

OBJECTIVE:

To create a manual mid-surface for the 3D model and generate the mesh.

PROCEDURE:

SEGREGATING GEOMETRY:

• Initially, geometry split into multiple surfaces regarding their geometry.
• Each surface locked with different views named with their thickness.
• Splinted surfaces then corrected for geometrical requirements.
• The surface which less than 0.5 are corrected or erased.

MANUAL MID-SURFACE:

• For each surface, one layer of the surface has been offset to its middle value of thickness.
• This process continued to all the view sets.
• After the creation of the mid-surface, each and every surface is connected with options like extend, interest.
• The final check for geometry has done an entire mid-surface saved in one lock view for meshing.

Fins:

• For fins, Curve -> middle option used to create a middle line on both ends.
• Then new surface created using those lines.
• This surface coon projected in the main surface and created contact between the main surface and fins.

MESHING:

• Surfaces meshed with a tool named
• Then meshes are checked for quality criteria.
• In case any mesh has not satisfied with the quality value, then that mesh re-meshed with option
• After that mesh group are smooth by option known as

PROPERTY ALLOTMENT:

• After completion of meshing, each surface view is assigned with property with thickness.
• Finally, mesh visual as 3D format and compared with the model.

CONCLUSION:

Finally given model has been created with a middle surface and meshed with 2D Quad elements. Each surfaces allocated with a thickness of its own.
