Week 6- Challenge

Follow the below-mentioned quality criteria, mesh the component given below and assign thickness:

Target Element Length = 5mm

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	8mm
7	Min angle Quad	45
8	Max angle Quad	135
9	Min angle Tria	20
10	Max angle Tria	120
10	Tria %	10

procedure

Import the model

Extract the midsurface for the each component

cleanup the component Mesh

Reflect the mesh

Check quality index

To import up the geometry.

Import the geometry by clicking on the import option and select import geometry

select the file type to STEP.

Browse and select the file to be imported

click the import button

The model is imported in the hypermesh and make it fit to the grapgical area using F Key

As the mode; consists of the various component we should extract the midsurface for the each components and do the topology cleanup

there are five components in the mod;e

Inner_extract_body1

outer_extract_body1

Hinge_reinforcement_extract_body1

Hinge_reinforcement_extract_body2

Latch_reinforcement_extract_body1

Midsurface extract

For the above five model the midsurface to be extracted and arrangement them according

The midsurface is extracted for the each component using the midsurface option from the geometry menu.

Now the midsurface as been extracted and renamed and given colour for each component as show below

Clean up

Now the cleanup has to be performed in the midsurface of the each component.

check for any defects in the midsurface by changing the geometry topology mode

Remove the defects.

Now go the auto cleanup option in the geometry menu and select midsurface to be mesh

toggle the unnecessary lines by using toggle edge tools & create lines where is necessary by using the split surf node and split surf line tool.

Meshing

After the autocleanup, go to 2d mesh menu and select automesh option,change the element size to 5,element type to mixed and select the midsurafce and click mesh tp generate the mesh.

Now the mesh as been generated for the component as shown below

After generation the mesh,check for the quality criteria,to perform the quality criteria,go to preferences option and edit the criteia as given in the

As shown below

Perform the same procedure for the all the components

For the inner extract body mesh cannot be done for the whole component so first half of the geometry meshed because the nodes exceed the student version

To mesh the other half,go to tools menu and select reflect and select the element to reflect,and duplicate the elements.change the vector selection to the required axis as and select the centre node of the complete geometry and click reflect

The reflect option can be done as shown below

Results and conclusion:-

Result: The give hood assembly is successfully meshed according to mesh quality provided and quality checked

conlusion: In the challange,we learn how to mesh the hood component

We learn amsk,reflect,quality,index and organize tools
