Week - 4 - 2D meshing for Plastic components

Aim

To extract mid surface of given plastic component and mesh the mid surface with given quality criteria.

Procedure

Step1: Import the geometry

first of all open ANSA software after opening go to file->open select the location of plastic component as shown below

Step 2: Topology & Geometry clean up

After importing CAD, Apply topo and perimeter & macros length as 1 than go to Tools->checks->geometry

Step 3: Mid surface extraction

for mid surface extraction of plastic component (Bottle cap), mid extraction technique like offset method, multi & single middle method and middle curve method is used.

Step 4: Assigning Quality parameter.

press fn+f11 to assign quality parameter as shown below.

Step 5: Meshing

Step 6: Assigning Thickness to all individual components

After extraction mid surface thickness is assigned to individual parts as shown below.

Step 7: Assigning Draw as shell as solid

Learning Outcomes

Able to apply different mid surface extraction techniques, mesh improvement technique, mid surface extraction of complicated geometry like teeth, thread and so on.

Conclusion

For the given Bottle Cap model mid surface is extracted with above mention technique, PID and thickness is assigned for the model and also meshed with given Element Quality Criteria. some quality failure at triple cons which is bound to be as shown above.
