Week 6-Meshing of Hood Challenge

AIM: To Extract the mid surfaces of the components in the HOOD model and to them mesh with the given quality criteria

PROCEDURE:

• import the model from the IMPORT MODEL deck
• press F if the mde id not visible on the screen
• chect the number of components present in the model from MODEL TREE
• delete all the solids from all the four component

NOTE: create, new components to work on and check the current component before starting , because if are working on component 2 , but the current set is on component 1 then all the working aspects are assoiate to the comp1 but not comp1

• make four new components for four new mid surfaces to be created
• extract the mid surfaces and associate them with , new components created in the MODEL tree

MID-SURFACE and MESHING:

• proceed one - by one for extracting the midsurfaces
• lets, move to the INNER component mid surface
• take the mis durface by , selecting surfaces>ATTACHED BY>create

NOTE: DON'T give the ALL optionas it select all th components other than the current working component

• as you can see there is an un attachment beteen the surfaces at the bending
• this can be coverd by creating a new surface

• create a mid line, as shown

• create a new surface SURFACES>LINE1/LINE2
• A Sharp edge is formed as shown in the omage

• give auto clean option , as it supresses (toggle ) the un wanted construction lines that give the error while meshing
• check all the supressed surfaces, if further supperesing is required, do it manually by, TOGGLE option
• subpressed should, as given that it should not effect the meshing quality criteria
• blue coloured dotted lines show the suppressed lines or toggled limes

MESHING:

• before the meshing give the qualitt criteria in CRITERIA FILES

• start the meshing AUTOMESH> ELEMENT SIZE>MIXED
• give the mesh, and go to quality index and see the number of errors that are happnening
• this can be reduced by, remeshing the selected area, smoothing them, or by elememt optimize or node optimize options

NOTE: WHILE meshing the components,seen there are in first order type

• the meshed emenents of all the components, are as shown

LATCH:

HINGE:

INNER HOOD:

OUTTER HOOD:

• THE FINAL meshed mid surfaces of all the components are as shown.
