Week 6-Meshing of Hood Challenge

OBJECTIVE

TO extract midsurface and geometry cleanup,mesh the compenet the size of 5 units mixed mesh,check quality parameters the given values.

CAD MODEL IMAGE

Cadmodel image of given component attached below.

PROCEDURE

first import the geometry.

extracted midsurface using midsurface option.

then find missing and duplicate surfaces and rectified those using delete surf and filler surf options.

then fixed washer plates to some surfaces to get a better mesh.

after geometry cleanup was done,mesh the component using automesh option in 2D mesh panel,meshing was done 5units mixed mesh.then corrected some irregular meshes to increase and decrease the nodes.

then go to tool panel using check elements option to set all the given values min and max length,aspect ratio,skewness,taper,min and max angles of tria and quads.then check one by one and rectify the problems using node edit ang smooth options.

then using quality index option to check the quality of mesh and rectify those irregular elements using cleanup tools which consists of following.

place node:using this to changed node to the right place .

smooth:using this to smooth all irregular elements.

element optimize:click the random places near the elements to rectify the quality issues.

combine tria elements:using this combined two trias by touching the centre line of two trias.

drag tria elements:using this dragged the trias which i dont want.

finally all the quality criterias are checked.

RESULT

Finally midsurfacing,geometry cleanup,meshing,quality checkups are successfully done.

final model attached below.
