Assignment 1-2D Meshing Challenge

AIM : 2D Meshing

OBJECTIVES : Geometry clean up, midsurface extraction, 2D mesh and assign proper thickness.

Given components

1. practice

2. Clip repair

3. Mounting Bracket

*DO's (These below steps has to be followed in each operation)

• Import the model
• 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.
• check with free edges and replace them manually/equivalance
• And assign proper thickness, by creating a generic property.

- Model 1
> After auto midsurface extraction, toggle the lines smartly so that a element can fit within the min/max size is alloted.
*F11 for quick edit, where many commands be founded like as toggle, split .



> Auto midsurface extraction (We can change options for it)
*geom--midsurf--surf--extract

> 2D meshing
*F12 for auto meshing

- After mesh we can observe some bad mesh, it can be rectified by remeshing.
- In this model, at bent surface more failure happens, so toggle them wisely.
- we can see the assigned thicknes by switching in toolbar
*Toolbar--2D detailed element representation.

> Final

- Model 2
> After auto midsurface extraction, toggle the lines smartly so that a element can fit within the min/max size is alloted.
*F11 for quick edit, where many commands be founded like as toggle, split .

> 2D meshing
*F12 for auto meshing

- After mesh we can observe some bad mesh, it can be rectified by remeshing.
- In this model, at bent surface more failure happens, so toggle them wisely.
- we can see the assigned thicknes by switching in toolbar
*Toolbar--2D detailed element representation.

- Model 3

> After auto midsurface extraction, toggle the lines smartly so that a element can fit within the min/max size is alloted.
*F11 for quick edit, where many commands be founded like as toggle, split .

> 2D meshing
*F12 for auto meshing

- After mesh we can observe some bad mesh, it can be rectified by remeshing.
- In this model, at bent surface more failure happens, so toggle them wisely.
- Here we can mesh at one part and rotate those elem by dulpicating them to other side by 90 degrees.
*Tools--rotate--elem--rotate+/-.
- we can see the assigned thicknes by switching in toolbar.
*Toolbar--2D detailed element representation.

CONCLUSION :

• Geometry clean up
• Midsurface extrtaction
• Meshing at small areas
• Mesh clean up
• Connectivity
• Thickness assigning.
