Project 1 - 2D meshing on the instrumental Panel

Aim:

To Extract the mid surface and good mesh flow of given instrumental Panel within quality criteria.

Given Geometry:

Givnen Quality Criteria:

S.No	Quality Criteria	Value
1	Target/Average length	4
2	Minimum Length	2
3	Maximum Length	6
4	Aspect	3
5	Warpage	15
6	Skewness	45
7	Jacobian	0.7
8	Minimum Quad Angle	45
9	Maximum Quad Angle	135
10	Minimum  Tria Angle	30
11	Maximum Tria Angle	120
10	Tria Percentage	15

Procedure:

¬ First open ansa and import the geometry , after give topology to whole part.

¬ After give topology all edge are connected and create as a double cons.

¬ Then check the geometry and clear all triple cons , crack as well the errors.

After Topology:

Geometry check:

¬ Clear geometry errors using right click of error and there option fix click it it wil be clear.

¬ Some error will not able to clear using fix option ,that will clear manullly.

Create mid surface:

¬ Manual Method used to create mid surface of the components.

¬ Change the dog house 

¬ Good mid surface taken for ribs .

¬ After mid surface taken go to check geometry as usual and clear the geometry errors, single cons are neglected.

Meshing:

¬ Now go to meshing intially change the perimeter length taken as a given target length.

¬ Select the whole part and give as a perimeter length as 4 mm.

¬ After give target value set mesh parameter and quality critiria as given question.

¬ Strat mesh using Bset and spot mesh using to start meshing the components area by area.

¬ Are else using Baych mesh option to get good mesh and time save also to be.

Clear quality issues:

¬  Using Split, join and swap options are used to clear the mewsh quality manually.

¬ Then smooth options clear the warpage errors by adjusting the mesh elements.

¬ Then minimum lenghth errors clear by change the element size by remove or add the element.

¬There are lot of ways to clear the falied elments in the mesh of Jacobian, warpage skewness etc.

¬ After used these method and clear all the quality issues.

¬After completing the meshing to assign the thickness of the midsurface.

¬Then use set PID option apply the thickness by creating property ID.

¬ Select the main part set thickness value .

¬ Then Different thickness value assign the thickness using mesured option

SEt PID:

Assign the thickness:

¬ After create PID go to quality parameter- presentation parameter and select Draw as shell as solid.

Learning Outcomes:

¬ Learn to create Mid surface for uniform thickness.

¬ Learn to take mid surface for ribs .

¬ Learn to take Automated midsurface.

¬Learn to mesh the model.

¬ Learn Batch mesh to model.

¬ Learn to clear off elements

Conclusion:

¬ The given components geometry check and cleared, mesh generated with the given quality criteria, After meshing different thickness to be  assigned  the given model sucessfuly.
