Assignment 1-2D Meshing Challenge

Report

Aim: Carry out the geometry cleanup operation on the given 3 files.

• Clean the geometry.
• Extract midsurface.
• Clean midsurface geometry.
• Ignore holes less than dia 5mm.
• Create 2D mesh with target length 5mm, min 3.5mm max 7mm.
• And assign proper thickness, by creating a generic property.

Procedure:

case1:

import geometry

use quick edit to clean up geometry

for example:

toggle lines

for example:

toggle lines and create surfaces:

for example:

delete multi-surface:

for example

delete and create new surface:

final geometry

extract mid surface

defeature fillet less than 5mm

set up quality criteria

create 2d mesh passed quality check

Assign material and property

case2:

import geometry

extract mid surface

create 2d mesh and pass the quality criteria

Assign material and property

case3:

import geometry

extract mid surface

create 2d mesh for a 1/4 part and pass the quality criteria

reflect the final mesh

Assign material and property

Conclusion: all 3 cases cleanup geometry, mid surface extraction, mesh creation and passed quality criteria.
