Week 6-Meshing of Hood Challenge

Aim: To generate mid surface and to generate mesh for the given geometry(Hood geometry).

Pre-requisites:

-Geometry

-HyperMesh software

Overview:

• Import geometry to Hyper Mesh software.
• Generate mid surfaces for each and every component.
• Generate mesh for each and every component.
• Equivalence the edges.

Procedure:

-Firstly, import the geometry to Hyper Mesh software.

 

-Select a component from the given geometry and clean up that component.

-Continue, the same for each and every component and clean up the component.

-Now, as we have finished cleaning the topology clean up for every component. Now, we can generate mesh for each and every component.

-As, we can see from the given geometry that this is a symmetrical geometry so we can delete one part of the geometry and can start meshing from the rest.(as shown in the picture)

-Now, as we have deleted the other surface we can generate mesh for the component.

-Repeate the same for each and every component and generate mesh.

-Now, we have genrated mesh for each and every component and now we should clean the mesh and should arrange in proper mesh flow.

-We have cleaned the mesh flow now, we need to give the given quality criteria for this geometry and mesh accordingly.

-As we can see that these elements are failing for minimum height as they are under the minimun height criteria, the given quality criteria minimum heoght is 2mm but here this fillet height is 1.8mm. Hence, we can allow this failure.

-Now, we need to generate symmetry for the deleted surfaces. To do that we have a tool 'Reflect', by using this tool we can generate the symmetrical surface.

-Now, for the faces created we need to join the edges, to do that we have a tool 'edges' select all the elements, set tolerance limit and preview equivalence and create equivalence. 

Objective:

From this week challenge, I have learnt how to clean the mesh according to the given quality criteria and to create a symmetry for the given geometry. 

Conclusion:

Mid-surface and mesh flow are generated for the given geometry(Hood geometry).
