Week 4

Aim:

For the given component, check for the geometrical errors and mesh with the given element Quality criteria. After meshing the component the thickness has to be assigned. 

Write a detailed report on your meshing process and also mention which method you used to extract the mid-surface along with the reason.

Solution:

 Geometry Check :

Using the fix command , these errors are removed

Manual Mid Surfacing :

 We will be creating the mid surface of the ribs as shown below :

The mid surface of upper part :

Using command such as offset , cons middle this middle surface on the outer side , for the inner side for ribs we have created curves as shown below :

We will use new cons command to create the mid surface of the rib as shown below :

 Now these inner ribs are extended as shown below :

Outer Ribs:

As you can see the outer ribs need to stitched and extended as shown below :

 The inner surfaces are created as shown below :

 Using the rotate command we get all the inner parts as shown below :

The whole mid surface of the part is :

Meshing : 

Setting the meshing criteria we get :

As you can see half mesh has been done which will be reflected on the other side

 After reflecting we get :

Since there are few elements which do not satisfy the quality criteria we need to do element clean up as shown below :

Conclusion:

Hence the given component has been mid surfaced manually and meshed with the maximum element cleanup possible.
