Week 4 - 2D Meshing for Sheet Metal

AIM:

To create a 2D meshing on the given Sheet Metal [WATER STORAGE SUPPORT BKRT RFD_MODIFIED].

PROCEDURE:

• First, we must find the thickness of each element in the given geomentry.

• Then I give the proper perimeter and Macro length as 1.

• I checked for geometry and removing the cons and error presented in the geometry.

• Now I create a mid-surface for all materials in the seat belt cover using different commands. Each element has a different thickness, like narrow structures, circultural element, taper, fillet regions and circular faces.
  • FACE
    • MIDDLE-SKIN
    • OFFSET

• As mentioned, I have applied the quality mesh parameters to the geometry.

• Next, I create a mesh on the mid-surface of each element in the Geomentry using the following commands.
  • MESH - BEST

• After creating the mesh on the mid-surface, we have to check the mesh flow for each element in the given geomentry and try to reduce the TRIA elements and OFF elements using the following commands.
  • Split
  • Swap
  • Join
  • Smooth
  • Reconstruction.

• Finally, After the smoothing the mesh flow, I obtained
  • Quad Elements - 24460 - 96.55 %
  • Tri Elements - 873 - 3. 45 %
  • Total Elements - 25333

LEARNING OUTCOMES:

1. I learned about various commands used in the ANSA for geometry clean-up, mid-surface generation and messing.
2. I learned how to use the swap, split and join commands to reduce the tri elements in a mess.

CONCLUSION:

2-D Mesh is successfully created on the given assembly.
