Week 9-Creation of 1D Connectors Challenge

Report on Connectors between two components

Objective-

Meshing of given CAD Models as per stated Quality criteria and provide stated connectors using Hypermesh.

CAD Model Image-

Fig.-1

Procedure-

1. Import the provided CAD Model and analyze it properly. If there exist any problem in model through Quick Edit & surface edit panel, rectify the problem and prepare the model for 2D Meshing so that minimum element size length can be achieved.
2. Now define the mesh quality criteria as shown in fig. 2.
