Assignment 1-2D Meshing Challenge

OBJECTIVE: The objective of this week is to clean up the geomentry, extract midsurface and create 2d mesh on the component satisfying the quality criteria and assign thickness accordingly to the component.

PROCEDURE:

COMPONENT - 2

Step 1: Import the model into hypermesh workspace.

Step 2: click on the wireframe geomentry to find whether there is any free edge on the component.

Step 3: For creating the midsurface, go to geomentry tab and click on midsurface button.Now select the surface for which you wanted to create midsurface and then click create button.

Step 4: After createing the midsurface properly you can start meshing the component.

STEP 5: Now mesh the component with element size as 5mm and element type as quad for rectangular surface and mixed for other surfaces.

STEP 6: After creating the mesh, there are chances that the mesh can be impropers at certain places anfd hece cleanup need to be done at those places.

STEP 7: The are certain options which you can use to clean up the mesh.

OPTION 1: You can just remesh the elements than needs to be cleaned up

OPTION 2: You can optimise the element by just clicking on it.

OPTION 3: You can place the node by just clicking and draging the node.

OPTION 4: You can also create, combine and split element by clicking on edit element option on the 2d panel.

STEP 8: After cleaning up the mesh elements now go to element check and see whether all the elements are within the given parameters.

STEP 9: After creating the mesh check whether the component contains any free edge. Go to tools tab and select edge option.now select all the elements and click create edge.Now the edges will be hilighted with red colour. If there is any free edge inside the component you can remove it by selecting the element around the free edge and click equivalence option.In case the free edge is still there you can manually edit it by replace option in 2D tab

STEP 10: Now create material and property in order to assign thickness to different surfaces.

STEP 11: Measure the Thickness for all the surfaces seperately and assign thickness to each surface accordingly.

Note: Repeat the above procedure in order to do for component 1 and 3

Conclusion: Thus for all the three component the mid-surface has been created and meshed by satisfying the quality criteria
