project-1: meshing and assign thickness of the car side door INNER PANEL

AIM:Evalute the quality criteria and mesh the component of car side door and assign thickness

OBJECTIVE:

Follow the Quality Criteria and mesh the following component and assign thickness:

Target Element Length = 4mm

ABSTRACT:

PROCEDURE:

GEOMETRY CLEANUP:

Import the geometry in optistruct profile.
Cleanup the geometry. and toggle the lines and create a cunstruction line for convinent for extract the mid surface

MIDSURFACE EXTRACTION:

Extract the mid surface by manually go to srface edit in geometry panel select the surface click on offset check vector normal hit on offset button than i would get midsurface of the specified part of the comoponent.
Before offset mention the off set value of the part. offset value is off of the thickness of the specified part
Geometry > surace edit > offset

Create the components based on the thicnes. after the offset move the mid surfaces reagarting to mention components

tools > oganice > collectors > surfacea > move

There is a gap between the ribs and lower mid surface. extend the ribs to lower mid

surface edit > extend > lines > surface > etend

UPLOAD CRITERIAFILE:

Fil the criteria file settings. go to preferences and click on the criteria file settings give the values regarding to given quality criteria

CLEANUP THE MIDSURFACE $ CONSTRUCTION THE LINES:

After extract the mid surface of the car side door model. create a construction lines on mid surface to convient for the doing mesh

PIC:CONSTRUCTING LINES

EXTENDING THE RIBS:

From parageometry etracract the ribs are extraccted with using manual midsurface

GEOM > SURFACE EDIT > OFFSET > VECTORNORMAL > OFFSET

GEOM > SURFACE EDIT > EXTEND

Go to surface edit in geometry and click on the extend slect extend over edges than sekect the mid of the rib lines to extend over end select surface to extend.than hit on exend ribs are extend as shown in pic

MESING:

While doing mesh try to reduce tria concentration on the corners and remove the trias at edges and fillets
After meshing i wolud get some failed elements like maximum length, warpages and miximum angle elements
clear all the failed elements and reduce tria concentratin in mesh
Below mentioned pics shows the mesh at plaine surface and cornr surfaces
drag the tria elements as possible

CLEARING FAILED ELEMENTS:

Clear the failed elements are many ways based on the type of failure like warpage issue , element length,angleand skew
these failed elements clear with uusing cleanup tools like elemnt opyimization, translate drag element

CHECK ELEMENT QUALITY:

After completing the mesh check the quality of the mesh. select F10 key from keybord its shortcut key for ceck quality of the mesh give the values from the quality criteria file and check one by one

If u get any failed elements save failed elements and mask and select the lements click on retrive than reverse the elements and clear the failed elements

FIND EDGES:

After completion of meshing check element quality than find the free edges in the mesh

TOOLS > ELEMENTS > EDGES

I Would get some free edges. than will go to tools select edges and elements displayed prview equailence than click on equalence . but i will get some free edges these edges clearing using with replace node option .than join one element with other element
