Week 9-Creation of 1D Connectors Challenge

AIM

      To mesh the geomentry and create conector under given quality criteria.

PROCEDURE 

• The given component is import as model formate.
• The component is viewed by topo mode. the geometry cleanup is carried out by manual cleanup
  method using the toggle option in quick edit
• Using the automesh option in the 2D panel, the given component is meshed under the given target
  element size and the component is meshed following the quality criteria.
• The above given qualiity criteria are given as input in the check elements option in the tools
  section.On meshing the components are meshed with quads and trias and the mesh is made proper
  by following various processes.
• The mesh with the rotating quad elements are made proper by selecting the rotation quads along
  with the nearby elements and remeshing them using the automesh option.
• The elements are aligned in a line by aligning the nodes of the elements using the align node option
  in node edit.
• The meshed elements are frequently checked for satisfying the quality criteria by using the check
  elements option in which the warpage, skew, length etc are checked for failures in the elements.
• The failed elements are then saved using the save failed option and are retrieved, masked and
  reversed using the mask option to display only the failed elements.
• Then the adjacent elements to the failed elements are unmasked using the unmask adjacent and the
  optimizing process is carried out.
• The failure of elements on quality criteria are made proper by various methods depending on the
  element failure in the mesh. The various methods followed to remove the failed elements in the
  mesh are
•  By using place node in qualiity index in which the node of an element can be moved to
  optimize the element.
• By using the element optimize option in quality index in which the element will be optimized
  based on the given quality criteria.
•  By using the split & combine element in the edit element option in which a quad element
  can either be splitted into two trias or vice-versa.
•  By using the smooth option in the 2D section, the elements can be selected and on
  performing this option the selected are made smoother by aligning the elements in a proper
  mesh flow with respect to the adjacent mesh flow.
• In case of any failure, translate option can also be used to fix the nodes of the element and
  the project option is used to place the misaligned nodes of the element over a surface
  edge.In case of any 2 opposite trias are found in the mesh, the 2 trias are made closer by
  using drag tria element in quality index and the trias are remeshed for removing them.
• Same process is done for all other surfaces.
• After the meshing create the conector using 

   1. Right_Rail_2 & Front_truss_1:- Seam-Quad(angled+capped+L)

• To create this conector is present in the 1d/2d/3d-conector-seam-type
• Select nodes by its path give 5mm for toloranc and spacing.then select tow components to create conector click create option. 
• 
• 

   2. Left_Rail_2 & Front_truss_1:- Quad elements

• To create this conector is present in the 1d/2d/3d-conector-seam-type
• Select nodes by its path give 5mm for toloranc and spacing.then select tow components to create conector click create option.
• 
• 

   3. Front_truss_2, Front_truss_1 & Right_Rail_1:- Spot weld with 2 Layers and 5 mm Diameter

• To create this conector is present in the 1d/2d/3d-conector-spot-type.
• Select nodes by its path 2layers give 5mm for tolarance and spacing and then create.
• Create conector for three surfaces is done by two pare one by one.
• 
• 

   4. Front_truss_2, Front_truss_1 & Left_Rail_1:- Hexa (Adhesive)

• To create this conector is present in the 1d/2d/3d-conector-seam-type.
• 
• 

   5. Rear_truss_2 & Right_Rail_2:- Bolt Connector

• To create this conector is present in the 1d/2d/3d-conector-bolt-type.
• Select one node and create conector
• 

   6. Rear_truss_2 & Left_Rail_2:- Bolt Connector

• To create this conector is present in the 1d/2d/3d-conector-bolt-type.
• 

   7. Right_Rail_1 & Right_Rail_2:- Spot-weld with Rigid Elements

• To create this conector is present in the 1d/2d/3d-conector-spot-type.
• 

   8. Left_Rail_1 & Left_Rail_2:- Spot-weld with Spring Elements

• To create this conector is present in the 1d/2d/3d-conector-spot-type.
• 

   9. Rest all the component left Join them with suitable connectors

• Same process is done for all other components by proper conectors.
• After creating the conector it turn to green if its still red in colour the conector is not in realized.
• Use realize option to create a proper conector.
• 
• 

CONCLUSION

       Thus the given component is mesh and created conectors under the given quality crireria.
