Week 3 - 2D meshing for sheet metal

Geometry cleaning

In this task firs I check all geometry with help of geometry check in check manager they show almost 50 problems.

Then select one problem and show only then after on naighb 1^st level then after solve the problems

And check again geometry check for the that particular regain then it shown it is 100% complete

After this click on focus all and check all geometry again.

Continue this until all the geometry problems was not solved.

Three are total 5 different part there so I set 5 lock view

Open each lock view one by one and generate mid surface with 2 different methods

1^st manual method with help of offset face

With help of this method, I make 3 mid surfaces of small parts witch thickness is 1.2mm (for practice)

2^nd automatic mid surface generate option

With help of this method, I make 2 mid surfaces of big parts witch thickness is 0.75mm (because those parts have huge no of faces)

Then set PID of all mid surfaces

Show only top part of hood mid surface

Apply mass on mid surfaces

Mid surface of Top part off hood is isometry so I cut the half portion and apply aliment length 5mm

And apply the quality criteria as given

Then check perimeter by manually remove unnecessary cons and hot points witch is not set in criteria

Then apply best mass and enable hidden mode so we can see quality criteria.

Then apply improve mass at quality criteria was not achieve

Then copy mass part and isolate symmetry for mirror

I Doit same process for bottom hood mid surface

And also apply mid surface to rest of the parts

New thing I learn in this challenge

What is the different types of quality criteria for mass how its work how to solve it manually

How to deal with symmetry parts

How to use feature area work and how its works.

conclusion

after performing this challenge we found good quality of mass with avenger 5mm cell length,

full fell quality criteria as per provaid and no any tria element at open edge
