Assignment 1-2D Meshing Challenge

AIM: To Generate the midsurface for the given component and mesh the component with given quality critera and mesh parameters.

PROCEDURE:

Step1: To import the given component into the gui

• File Menu>import>Model>Select the file>Import.

Step2: To perform the geometry clean up for the given component

• Switching to topo mode to check for geometry.

• To fix incomplete geometry or open surface

• The above image shows that the edge is not shared or attached to the adjacent surface which is indicated in red color which is a single con.
• Now to fix the above surfce using toggle option to combine or stich the 2 surface together, now the con is indicated in the green line.

• To fix the below open surface as shown in below image.

• Using replace point option to fix the surface.
• F11 selecting the point to replace.

• `Now the surface has been fixed and closed.

• Now to fix above protruding surface
• using split by face to delete the protruding surface.

• Shift F9 or Geom>surface edit seleting 2 surface.

• F2 or using delete surface option to delete the protruding surface.

• Using toggle option to stitch the surface.
• To delete the duplicate surface .

• F2 or using delete surface option to delete the duplicate surface.

• Now the geometry is fixed.

Step3: To prepare the component for meshing to avoid element failure also to get the better mesh by using defeaturing.

• Now measuring the fillet region using distance option.
• The fillet distance is less than minimum size of the element.

• Using defeature options to remove the fillet
• And create the middle line in the fillet region.

• Filling the holes which is less than 5 units in dia.

• F11 or quick edit to fill the hole. geom>quick edit>filler.

Step4: To mesh the given component with given parameter.

• F12 or 2d>automesh>selecting the surface.
• Selecting the element size>mesh.

Step5: To fix the quality of the element

• Using distance option orF4 to remove the minimum and maximum quality by moving the node accordingly
• Used element optimization from element clean up tool.
• fixed the quality.

Step6: To check for the conectivity issues.

• Shift F3 or Tool> edges option and provide tolerance
• The free edges are highligted in red colour.
• Using equivalence option to connect the edges.

Step7: To Assign the property and materials for the given component.

• Right click on the menu bowser and select create
• By giving the thickness to the property
• Also selecting the material cards
• Now right clicking on the components>Assign>selecting the property.
• The material and property is assigned to that component.

Following the same procedure for the other given components.

Final Pictures of the given models:

RESULT: Successfully Created the midsurface and meshed all the 3 given component with given quality criteria and mesh parameters.
