Assignment 1-2D Meshing Challenge

AIM: carry out geomatric cleanup operation in given models

PROCEDURE:

model-1

make the model in topo mode
there are several surfaces ara missing in geomatry so we want to do geomatric cleanup in parent surface

we want to create missing surfaces for that we use ruled option in surfaces , toggle edges by setting tollarance value
need to delete unwanted surface in model and also need to delete a duplicate surface
then check for geomatry is it uniform thickness or not , this geomatery is uniform in thickness
we can extract the midsurface by using automidsurface option
go to misdsurface option and go to midsurface option and set offset+planes+sweep
then select the surface and do auto midsurface extraction

in midsurface we need to do some geomatric cleanup to avoid minimum element failure
replace adjucent point to one by using replace option in quik edit option
by setting midline option toggle the feature lines to avoid minimum element failure
toggle the holes below 5mm radious by using unsplit surface option and toggle unwanted feature lines
then we can start meshing on surface
do mesh on each part of mid surface
before meshing we need to set quality critirias as min size: 3.5 max size : 7 and target element : 5
while meshing always keep equal nodels in sqaure surface to avoid trias
use rebuild mesh option to get better quality mesh
remove all minimum element failures by adjesting its lenth in using distance option

here we got the geomatry with perfect mesh
then we need to do normal check
check for free edges if any use preview equalance to see disconnected mesh and do equalance
then we need to assign thickness to mesh
measure the thickness (.9)
create property and make thickness = .9
then assign property to mesh

fig: final output of mesh to given mode-1

MODEL-2

do all geomatric cleanup as per done one model-1
toggle unwanted feature lines
eliminate holes below 5mm
replace adjusent points
then extract midsurface by using automidsurface option
in this geomatry we can only need to mesh some surfaces and we can copy mesh into similer surfaces
for this use position option then duplicate the mesh and postion to surfaces
always do above mentioned(model-1) procedures for meshing

here we got the geomatry with perfect mesh
then we need to do normal check
check for free edges if any use preview equalance to see disconnected mesh and do equalance
then we need to assign thickness to mesh
measure the thickness (2)
create property and make thickness = 2
then assign property to mesh

MODEL-3

do all geomatric-cleaunup do as procedure done in above 2 models
while meshing use positioningoption
and aso we can do reflect option by done in 1half and re3flect to remining surface

here we got the geomatry with perfect mesh
then we need to do normal check
check for free edges if any use preview equalance to see disconnected mesh and do equalance
then we need to assign thickness to mesh
measure the thickness (2)
create property and make thickness = 2
then assign property to mesh
