Week - 4 - 2D meshing for Plastic components

Aim: To create mid surface for the given cad model and perform 2d meshing then convert to 3d mesh.

Outline:

*Importing the cad model

*doing geometry check up.

*rectifying errors.

*mid surface generation.

*meshing 

*improving the quality of the mesh

*applying thickness to the mesh

Procedure.

*Importing the cadd model into ansa.

*performing topo for the model. then tools-checks-geometry for checking any geometrical errors.

*creating the mid surface using faces-offset,middle,middle-multi, curve-middle & faces-new. since it is having varying thickness everywhere. Doing mid surface clean up by deleting unwanted hot points and cons.

*appling quality criteria, mesh parameter values then meshing-best mesh. By using reconstruction, smooth, split, swap, insert hot points, option to improve the quality of the mesh.

*applying thickness to the mid surface and checked draw shell as solid.
