HYPERMESH_PROJECT 1 - MESHING THE INNER PANEL OF CAR'S SIDE DOOR

AIM :

To Mesh the given platic component and assign the variable thickness to different parts in the component.

GIVEN QUALITY CRETIRIA :

GIVEN COMPONENT :

PROCEDURE :

Step 1 : IMPORTING THE GEOMENTRY

Importing the geometry of the given model as HYPERMESH file by using the tool as import geometry.

STEP 2 : CHANGING THE MODE

Change the color geometry mode from Auto to By Topo
We select the By topo method because it is the handy option that is used to identify the free edges, shared edges, T-Junction, and Suppressed edge.Now, clean up the solid part If any present in the Geometry
This also helps to find out the surface and solid in the components

STEP 3 : SPLIT THE COMPONENT

To simplify the midsurface extraction we can split the main component into sub components
In this i split the side door into 4 sub components
For this process i use the TRIM WITH PLANE feature in the surface edit panel.
Then select the whole component, and select the axis that i need to split

STEP 4 : SURFACE CLEANUP

Always do the manual cleanup for the component.To do this press F11 or Go to Leanup Tools
In this menu you can perform the various operations like Toggle, split, washer split, etc based on the cleanup require for the given component.

STEP 5 : MIDSURFACE EXTRACTION

After spilitting the component, we need to extract the midsurface one by one by manual
Before that, by using the organize command, assign the sub components into different collectors.
For this midsurface, i use the OFFSET command.
Before offset the suface, create the new collector for saving the midsurface for current component
And make this collector as current component
Now measure the distance between the two surfaces
Then go to the OFFSET feature in the surface edit command
Select the surface that you want to offset and make it as duplicate
Reapeat the same process for all surface in the components

STEP 6 : CHECK THE CONNECTIVITY

Before meshing process, always fix the connectivity issue between the surfaces that we offset
We can solve the connectivity issue by using the EXTEND, TRIM WITH LINE, TRIM WITH SURFACE featues
And finally it looks like image that shown below
In this yellow line indicates the intersection of three surfaces
And green line indicates the intersection of two surfaces
And red line indicates the free edges

STEP 7 : MESHING

Meshing is a part of the simulation process where complex geometries are divided into simple elements that can be used as discrete local approximations of the larger domain.
The mesh influences the accuracy, convergence, and speed of the simulation.
Click the F12 or select the automesh option in the geomentry menu.
Automesh option is used for meshing a surface with 2D elements
Change Geom mode as 2D in the Mainmenu bar
Then select the Automesh option

STEP 8 : QUALITY MATCHUP

STEP 9 : CHECK THE FREE EDGES BETWEEN THE ELEMENT

Afetr meshing, we have to check the edges between the elements
If you have any edges inbetween the elemets, use the equilence option to fix this issue
And we can also use the replace option

STEP 10 : ASSIGN THE THICKNESS

FINAL COMPONENT

RESULT :

Thus the given component is meshed under the given quality cretiria and assigned the thickeness for whole component.
