AIM:
For the given Plastic Bottle Cap model, check for the geometrical errors and take the mid surface by suitable mid surfacing techniques. PID and Thickness assignment has to be done for all the mid surfaces. Mesh the same with given element Quality criteria. (Refer the table Below for the Quality criteria)
S.No Quality Criteria Value
1 Target/Average length 1
2 Minimum Length 0.5
3 Maximum Length 3
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
OBJECTIVE:
The model of 2D plastic componenet having different learning outcomes are proper meshing of the object and check the geometry for the model and make a midsurface with manual method and connections are made with given quality criteria.
PROCEDURE:
*To make the model to download the object and open it in ansa software first of checking the model geometry elements cleaning process.
*Topo mode select and select the object middle click on the mouse topo mode is activated.Now for the orient selection getting the element having single colour on all the part with the position it could be yellow or ash colour.
*Checks manger/geometry/ececute/right click fix the errors on it.Then check the error topo and tripple cone and single cone errors release it geometry errors are cleaned.
*Making mid surface for the model auto mid surfacing is not get proper so selecting the offset method measure the width of element and checks the width and midsurfacing parts by parts and make it for all the parts.
*For meshing quality criteria is put as per the question elements create element size quality elements all the factors and check it in correct.for checking failing elements occuring in these part clean all the parts by remeshing elments else change the improve smooth it and clear all the error portions on the design and make it free.
*Now assign the thickness of the design with creating the right click option and thickness are assigned with it on given amount.For that make the part should be save on a proper file with file save as option.
RESULT:
Make the model mid surface and meshed the plasic componenet.
