Week 9-Creation of 1D Connectors Challenge
Aim :- For this challenge, you will have to mesh the given geometry. Provided below are the quality parameters that you have to follow. Create connector and Attach the various parts of the given model .
Ans :-
I) Model Import and Geometry Cleanup :-
First import the model using import option, then we have to do geometry cleanup for 2D meshing purpose.
for geometry cleanup, Geom - autocleanup - edit criteria and parameters - select surfs - autocelanup.
II) 2D meshing :-
Given model consist of different components, so we have to do 2D meshing seperately of element size 5mm for good mesh flow qulity .
for 2D meshing, 2D - automesh - select surfs - mesh type - element size - mesh.
III) Quality criteria :-
We have to give quality criteria for mesh as below

For given quality criteria we have to remesh or rebuild mesh for good quality of mesh.
IV) 2D mesh component :-
V) Property and Material Assigning :-
VI) Connectors :-
For connectors we have to open connector panel from view - utilities - hypermesh - connector.
1. Right_Rail_2 & Front_truss_1_Seam-Quad(angled+capped+L) -
1D - connectors - seam - nodes (by path) - search tolerance - select comp. - seam type Seam-Quad(angled+capped+L) - spacing distance as 5 mm - create.
