Assignment 1
OBJECTIVE
The aim of the project is to clean up the geometry for the given files & mesh the compound by creating a mid surface and assign proper thickness & generic property.
Case Setup
Model - 1
a) Geometry
The 2D topo mode is used to visualize the single, double & triple cons. Each type is represented by a different color,
Single con - It denotes that edge is not shared by any edges & represented by red color, Double cons - It denoted that edge is shared by other edge & represented by green color, Triple cons - It denoted the edge is shared by two edges & represented by yellow color.
The delete --> lines --> displayed --> delete entity - This option is used to delete the extra lines which are not connected to the component.
The Single cons & triple cons are error as the edge needs to be shared by a single edge to create a closed geometry.
Geometry --> quick edit --> Toggle - This option is used to join the single cons together double join.
Geometry --> quick edit --> Filler surf - This option is used to create a surface.
Geometry --> Surface edit --> trim with surf/plane - This option is used to trim the extra surface from the actual geometry & delete surface is used to delete the extra surface.
b) Cleaned up Geometry
Geometry --> Mid surf --> Auto --> choose the surface - This option create a mid surface.
c) Mid surface extract
The hole size less than 5mm is not consider for the meshing & are filled using the filler option.
The auto mesh option is used to mesh the shell element. The mesh style & smooth tool are used to keep the flow of the mesh proper & element shape.
d) Mesh
2D --> Quality index --> cleanup tools --> element optimization is used to eliminate the quality criteria failures. The minimize size criteria is cannot be achieved since the fillet has a size less than 2mm so we need smaller elements to capture them.
e) Quality Criteria
The quality criteria range of the elements
Model -2
a) Geometry
Geometry --> quick edit --> add/remove point --> right click to remove the extra points.
Geometry --> Mid surf --> Auto --> choose the surface - This option create a mid surface.
b) Mid surface extract
The hole size less than 5mm is not consider for the meshing & are filled using the filler option.
The auto mesh option is used to mesh the shell element. The mesh style & smooth tool are used to keep the flow of the mesh proper & element shape.

d) Quality Criteria
Model - 3
a) Geometry
Geometry --> quick edit --> add/remove point --> right click to remove the extra points.
Geometry --> Mid surf --> Auto --> choose the surface - This option create a mid surface.
c) Mesh
The hole size less than 5mm is not consider for the meshing & are filled using the filler option.
The auto mesh option is used to mesh the shell element. The mesh style & smooth tool are used to keep the flow of the mesh proper & element shape.
d) Quality Criteria
2D --> Quality index --> cleanup tools --> element optimization is used to eliminate the quality criteria failures. The minimize size criteria is cannot be achieved since the curves are very close to each other & in order to capture them min size quality criteria is not considered.
