Week 12 - Project-1
AIM:To get the manual mid surface of the component along with the good quality of mesh flow deployment taking a given a quality criteria in the component.
PROCEDURE:(i)The model which we have got after importing it into hypermesh radioss is shown below:

(ii)Firstly we have got to remove all the solids present if any since it is a 2D plastic model of side door having the varying thicknesses.
(iii)Now for the sake of simplicity we can divide the model into many parts assigning it into different component or else we can take the model as whole,dividing the model leads to proper mid surfacing of the component because it is a plastic part.Here the has been divided into the 4 component which has been shown below:

(iii)After Organize>Tool image shown above looks alike,now we can take out the mid using surface>offset and making componet duplicate and make as current then in offset we choose duplicate as well then mid extraction along with connection should be make in the part of mid which can be done by various options like extend,trim to surface or edge etc doing so the mid model with connection shown below:

(iv)Then we assign a different parts of the component to different thicknesses to do that we have got to assign that component separately according to there thicknesses likewise we can assign different properties of different thicknesses of card image as p-shell shown below:


(v)Then we proceed to the meshing part with a quality criterion shown below:

And then we give the automesh and meshing the component continuously until we woulldn't get the result of meshing having low trias with very low quality failure having proper quads mesh flow with no rotating quads.
(v)Then for making nodes to nodes connection we can go to tools>edges and give equivalences with different values of tolerance could vary from 0.1 to 1 if then also connection required we can do it manually by using the replace option of F3 after deploying necessary connection with meshing model and assigning the thicknesses and enabling to 2D traditional and detailed element representation model shown as below:

(vi)If doing meshing properly is not capable enough to remove quality issues then we prefer to choose 2D>Quality index and cleanup tools to get rid off most of the quality failures.Image shows below of it.

CONCLUSION:(A)Here we have got to know about the meshing in a plastic component and how to seggregate the mid surface of the same component.
(B)Here we have understood about the defeaturing of the lines in order to get good mesh flow and quality also got it about how unnecessary defeaturing distort the model.
