Week 3 - 2D meshing for sheet metal

AIM-Take the mid surface for all the components after checking the geometrical errors and mesh the mid surface with the given element Quality criteria.

1	TARGET ELEMENT SIZE
2	Minimum Length	2
3	Maximum Length	7
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

STEP 1 . Import the given CAD model

go to file import / open and select the given model and open

STEP 2. check for quality

go to the check option in the tool bar and select geometry and if any errors are found fix auto

step 3. Once geometry is done select topo under the topo module and hit middle mouse button after selecting the part

step4. do manual clean up using cut and join under topo or mesh module

step5. remove all lines or join the lines which may void quaality parameters

step6. enter all the quality criteria as given above and mesh each component one by one

step 7 once meshing is done , check for failing elements and reconstruct them again and again

step8. once meshing of all components or parts is done hit join option and select all component and select keep mesh and hit middle mouse button

step 9. export or save the document

here are some snapshots of the process
