Week 12 - Project-1

Follow the Quality Criteria and mesh the following component and assign thickness:

Target Element Length = 4mm

S.N	Quality Criteria	Value
1	Aspect Ratio	5
2	Skewness	45
3	Warping	15
4	Taper	0.5
5	Min. Length	2mm
6	Max. Length	6mm
7	Min angle Quad	45
8	Max angle Quad	135
9	Min angle Tria	20
10	Max angle Tria	120
10	Tria %	10

Importing the model.

Creation of Missing Surfaces:

Geom -- > Surfaces -- > Splines/Fillers

Creation of node:

• Geom -- > nodes . Section of line and create the required nodes.

The split surface along node:

• Geom -- > surface edit -- > trim with surfs/plane

• Select the surfaces to trim and the node and direction along which it is to be trimed is set.

• The surface is split along the node and direction given.

• For the ease of creation of manual mid surface the different half’s of the surfaces are kept in different components.
• Tool -- > collectors. The surfaces to move are selected and the component destination is set and click move and the selected surfaces are moved.

• The selected surfaces are moved.

Defeature:

• The surface fillets that are less than the required radius are found and removed.

• The fillets are removed.

Manual Midsurface:

• The manual mid-surface is created.

Creation of Mesh: 2D -- > automesh

• 2D mesh is created.

Similarly:

• The manual mid-surface is created.

• 2D mesh is created.

Edge detection :

Tools -- > edge

• Equivalence is used to join the elements on the edges.

Similarly:

• For the other surfaces, the manual mid surface is created.

• The manual mid-surface is created.

• 2D Mesh with target element size is created.

• Check elements are used and all the elements are to check the quality criteria and set them all.

• Find the edge and equivalence the edge elements.

• Check elements are used and all the elements are to check the quality criteria and set them all.

Conversion of 2D elements to 3D:

• Geom -- > distance. Distance between two is found to find the thickness.

• Different surfaces have different thicknesses.
• So elements with same thickness are kept in one component for the ease of assigning the thickness.

• Property is created.

• The property is named the same as thickness for the ease of assigning.
• The required thickness is entered.

Similarly :

• All the elements of 2mm thickness are moved to one component “Middle surface 2.0”.

Assigning Thickness:

• Thickness is assigned to the component.

Similarly, all the elements with the same thickness are moved to one component are thicknesses are assigned respectively.

• The final image of a fully completed model.
