Week 6-Meshing of Hood Challenge

AIM:

To mesh the parts of hood with given quality certiria to satisty the industrial needs of the given part.

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

Target Element Length = 5 Units

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

Software requried:

• Hyper mesh student version or orginal version

Procedure:

• Import the file from the challenge fodler of skill lync and save the IGES files

• Model is spilted into four parts as LATCH, HINGES , INNER EXACT AND OUTER EXTRACT .

• So we start the by creating midsurfaces for all four parts and save them spearately to get esaily identified the pats well.

• Rename the midsurfaces so we can work in it, Then we toogle the part and make spilts by node and divide the lines and keep it easy to mesh.

• Mesh the latch well by the given spilts as per the quality certiria and see to that we dont have any connectivity issues and trias in the mesh and maintain the quaity of the mesh .

• Finish the LATCH meshing and check for any quality issues if we have any isses save the failed area and go to mask > reterive >mask all > rervese to unmasked area now we can work on the faling area and make it ok .

• Now select the hinges part and hide the surface and midsurface area so we can fully use the hinges area well and work on it .

• Following the same steps we had before and spilt and toogle the surface well so we can mesh properly and satisfy the quality certria well .

• Mesh step by step in the spilted area and always have a flow so we dont get connection issues and spend time in correcting them .

• And save the quality certiria in the preferences so we dont mesh for the wrong not given qualty opition .

• Now the right side of the hinge is ciompleted hide that side and unhide the left side of the part, And mesh the left side .

• Hide the hinges part and open the outer extract part now here we have a task we should create a MIDLINE in the converging area so we can capture the area in the maxium level keep on line in the middle ans toggle the remaining lines .

• Now spilt the outer extract in an eqaul rectangles and toogle the unwanted feature line now we can mesh the spilted area well and follow the flow and mesh the outer extract part.

• Correct the mesh with good connection in thes mesh and less traias as possbile and pass all the quailty certria also with it .

• Hide the outer exract part and open the inner exract part .

• Now open the inner extract and make the midsurface easy to mesh by toogling and spilting the surface as many spilts and mesh it properly and make sure tht we are doing it only in the half of the surface only so we could relefect the half.

• Then go for tool>refelect > select elements > dupilicate all > current compoents > select the axsis > y axsis > select the base in the middle of the parts to get even refelction of the mesh and look foe any asymentrial mesh and correct it properlty are any over lapping mesh elements and delete them finally check foe free edges and conform noone is present in the unwanted areas.

BY THIS WE COMPLETE THE MESHING OF THE HOOD WITH THE GIVEN CERTIRIA THE FLOW OF THE PROCESS IS ATTRACTED WITH THE PICTURES GIVEN BLEOW .

The parts of the hood before meshings

Result:

Thus the given part model is meshed by given quality and submitted to the industirial needs .
