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.

                                                                        c) 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.

                                                                   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.
