ASSIGNMENT 1

OBJECTIVES:

To Carry out the geometry cleanup operation on the given 3 files.

• Practice
• Clip Repair
• Mounting Bracket

There should not be any free edges, convert all of them into refine geometry.

• Clean the geometry.
• Extract midsurface.
• Clean midsurface geometry.
• Ignore holes less than dia 5mm.
• Create 2D mesh with target length 5mm, min 3.5mm max 7mm.
• And assign proper thickness, by creating a generic property.
• Then Save in .hm format.

PROCEDURE:

• Import the model file into the hypermesh.

• Then create the midsurface of the component by geom – midsurface – extraction – offset+planes+sweep – auto midsurface – select the surface – extract to create the mid surface of the model.

• The auto cleanup the mid surface geom – autoclean up – select the surface.
• Then mesh the component 2D- automesh – select the surface – mesh, give the element size 5 and select the type quad.

• Then give the quality criteria in tool – check elems.

• Tools used to meet the quality criteria by 2D- quality index – clean up tool.
  1. Place node is used to move the nodes
  2. Node and element optimize is used to optimize the element automatically.
  3. Smooth is used to smooth the curvature.
  4. Drag tria element is used to drag the tria element out.
  5. Spilt quad is used to split the quad element into two quad.
  6. Combine tri is used to combine tria elements into quad.
• Tools used to meet the quality criteria by tools
  1. Mask is used to mask the failure elements.
  2. Edit element is used to create, split and combine the elements.
  3. Replace is used to replace the nodes.
  4. Tool – translate – elements – select the surface.
• Then give colours to the component to differentiate.

RESULT AND CONCLUSION:

• Learnt how to do 2D mesh, geom cleanup and extract mid surface of the component in given quality criteria.
