Week 6-Meshing of Hood Challenge
OBJECTIVE:
to mesh the component by using the given quality criteria below and assign thickness.
S.N Quality criteria value
1 aspect ratio 5
2 skewness 45
3 warping 15
4 taper 0.5
5 min. length 2mm
6 max. length 8mm
7 min, angle quad 45
8 max angle quad 135
9 min angle tria 20
10 max angle tria 120
11 tria % 10
target element length = 5mm
PROCEDURE:
1. first of all go to import solver go to Deck>import geometry>file
type: STEP>choose file > import the geometry is imported.
2. then go to feature tree>components>hide all the components except inner_extract_body1.
3. delete >solids>select all>delete.
4.geometry colour mode> by topo.
5. geom> midsurface>surfs>select all> extract.
6. to cleanup the geometry use these option.
f11> filter surf > lines> to fill the gapes.
f11>toggles edges > by changing the tolerance value fill the gapes /suppose some line which are below target element size.
f11> split surf-line> to delete and recreate a new line.
geom> surface>spline/filler or ruller or skiun these option are used to the cleanup free and non manifold uses.
7. after the cleaning up the geometry , go to 2d> automesh>surfs> displayed>element size :5mm > mesh type: mixed > mesh. after meshing is done , go to feature tree delete the componnt .
8. check the mesh flow . and then remesh the improper mesh area .
9. F10 > quality criteria > enetre the given criteria.
10. to check the indivisually all type element in which the value has been eneterd.
11. some element fail in this quality criteria , they can rectified by using some options .
tool>check elements > save failed.
tool> mask >elemts >select elements>mesh( some failed elements can be removed by remeshing them)
2d> qualityindex > cleanup tools > display threeshold : fail> there are lot of option there is clesnup tool, by using these option we can remove the failed elements.
12. and again check elemets in the given quality criteria . if there is no elemets failed then the components is perfectly meshed with the given criteria .
