Week 12:Project 2-Meshing of Rear Wheel Holder challenge

OBJECTIVE: 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

CAD MODEL IMAGE

PROCEDURE:

STEP1:Import the model into the hypermesh graphical area using the import option

STEP2:Check for geometry cleanup,defeature sharp corners,triplecons,freeedges and clean the geometry to obtain proper mesh.

STEP3:The midsurface is to be created for shell meshing,To do this first check for component thickness by using distance option.

STEP4: Using the offset option in surface edit panel,offset the top surface to half the thickness by specifying the vector normals.

STEP5: Also,we can opt for auto mid surface as it is a sheetmetal component with uniform thickness.

STEP6: Next,start meshing by using the automesh option in 2d panel, from the critical region in the centre,mesh towards the outer side for a proper mesh flow,

STEP7:Check for element quality criteria as given in the question.

STEP8: If any element is failing using the quality index option try to fix them

.STEP9: Make sure all the elements are passed for the criteria given.

STEP10:Next,check for edges in the model by using Tool-edges.

STEP11:Make sure there is proper connectivity between the elements.

STEP12: Check for normals and try to adjust them if there are any errors.

STEP13:Next step is to assign thickness,create a property and enter the value for thickness in the property and assign the property to the midsurface

STEP14:Check for the assigned property by 2d detailed representation.

CONCLUSION:The model is meshed for the following criteria and thickness is assigned
